How to update the time on Windows 7. Lost time: clock failures on the “seven”

Many computer and laptop users very often complain that the time on their devices is constantly lost, so it has to be corrected periodically. Moreover, as practice shows, almost all of us face this problem sooner or later. Why is this happening? How to deal with this problem? We will tell you about all this right now.

Changeover between winter and summer time

Just a few years ago in our country, every autumn and spring we moved the clock hands back or forward one hour, respectively. However, then the government decided to cancel the transitions. That's just the operating room Windows system, whether it's XP, Vista or 7, still automatically moves the clock!

On the Date and Time tab, select Change Time Zone....

In the window that opens, uncheck the box that says “Automatic switch to summer time and back." For more details, see the screenshot:

Synchronization with the server

There is a problem of a different nature. Default to operating systems ah, there is an update, which also affects the current time. In other words, as soon as you go online, the system automatically synchronizes with the server and automatically updates the time for your time zone. And since not all servers yet know that in Russia the clock hands no longer change, such a mess occurs.

The solution is very simple. Click on the clock again, click on “Change date and time settings...”, then select the “Internet Time” tab.

Click Change Settings. Uncheck the box next to “Synchronize with an Internet time server” and click OK. That's it, synchronization is now completely disabled.

Battery on motherboard

If you used the two methods described above, but it did not help you at all, then the problem most likely lies in the battery on the motherboard. Many will be surprised - a battery? Which one is this? It's actually very important element any computer or laptop.

This battery is necessary so that the system can store data on system settings, because otherwise, every time the PC is turned on, this data would be lost and then new settings would need to be created each time. Of course, this is incredibly inconvenient. The battery is very helpful in this regard, and its service life can be calculated in decades, although it usually lasts 5-8 years.

It is installed on the motherboard and it is very easy to find it yourself - just look at the board. Replacing it is also easy, but remember that this must be done strictly with the power of your PC turned off. This battery can be purchased at any store that sells computer components; it is inexpensive. After replacing, you should completely get rid of the problem.

Motherboard problem

Even if after replacing the battery the time continues to reset, then perhaps one of the elements of the motherboard has died. It is very difficult to figure out this problem on your own, since apart from “temporary difficulties” there are no problems, so we recommend taking the “motherboard” to service center for diagnostics.

The Windows clock is located in the lower right corner of the screen on the taskbar next to the “ ” button, the language bar, and other elements and opens by pressing the left button on them. In order for the system clock to show accurately, it is necessary.

Synchronization occurs with the Internet server and your PC time is automatically updated. By default, updates occur every 7 days as long as there is an Internet connection. In the article we will look at how to enable synchronization, how to speed up time updating with the server, and what program you can use.

How to enable and configure time synchronization on Windows 7, 8

Note: Internet time synchronization is enabled by default in Windows.

To get started, you will need to select small or large icons in the viewing area. Next in the list, click “date and time”.

This will open the date and time options. You can also call them by left-clicking in the date and time display area and select the corresponding link (shown in the screenshot).

In the window, go to the “Internet time” section; here you will find information about the current synchronization with the name of the server (if it is enabled). By default, Internet synchronization is performed with a Microsoft server called time.windows.com. To change settings, click “change settings” and “yes” (if User Account Control is enabled).

In the Internet time settings, the option “ synchronize with time server" Select one of the pre-installed servers or define your own (the list of servers can be found here http://support.microsoft.com/ru-ru/kb/262680). Next, click “update now” to synchronize the time on your computer with the Internet. If synchronization is successful, you will see a notification in the same window.

To synchronize time via the Internet, you can use various utilities such as:

Atomic Clock Sync
NetTime
SP TimeSync
Other

All aspects of synchronization are configured through the programs, and the update request interval is reduced. Standard methods You can also synchronize the time on your computer with the Internet faster and more often, read on to find out how to do this.

How to reduce the time update interval from the Internet

There may be a situation where the time is constantly lost due to problems with the system clock, even if you have time synchronization enabled on your computer. The solution to the problem is to edit the NTP client to speed up the update period. Depending on the OS version you will need:

In the registry, go to the NtpClient section ( full path shown in the picture below). IN right side editor, double-click on the SpecialPollInterval parameter. Next, in the number system area, select "decimal" and the value field will contain the number 604800, which represents 7 days in seconds.

For example, if you want to synchronize the time on your computer with the Internet every day, then enter the value 86400, which is calculated using the formula 60 seconds * 60 minutes * 24 hours * 1 day. Set your number of seconds and click OK.

Note: Do not set the value less than 14400 seconds (4 hours), otherwise your computer's IP address may be blocked by the time server.

You can also speed up syncing manually, but getting to the "update now" button is a lot of steps. IN in this case you can use cmd. To do this, you need to , 8 as administrator, and then enter the command below and press enter.

Note: the command will work if time synchronization via the Internet is enabled.

To speed up the process further, copy the synchronization command into it. Next, place the file on your desktop or pin it to the taskbar and run it as administrator.

Preventing problems during synchronization

Install exact time It is not always possible to synchronize with the Internet. You may encounter the following problems and solutions:

Make sure that the time zone, date and time are manually set correctly on your computer, otherwise you will have trouble trying to synchronize your computer clock with an Internet time server.
Windows gets its initial time from the BIOS, so make sure the time and date are set correctly in the CMOS BIOS.
Check the CMOS battery on the motherboard. If it is weak, then your clock may run slower, losing or resetting time. If so, then you simply need to replace the CMOS battery.
If your computer does not keep accurate time even after enabling synchronization and changing time servers, read above about changing the update interval.

As you can see, synchronize the time on your computer with the Internet in Windows 7, 8 for accurate display is not difficult. Everything can be done using standard Windows steps. The programs will only reduce the cost of your time, for example, they will reduce the synchronization time in two clicks.

In fact, synchronizing time in Windows 7 is very simple. Now you can see this for yourself.

The first thing you will need is access to the Internet. If you are already online, then just follow a few steps.

Click on the clock located in the system tray.

A window will appear "Date and time" with three tabs. You need to go to the tab "Time on the Internet."(By the way, the word “Internet” is written with a small letter).

Which server to synchronize time with?

So, you have switched to the “Internet Time” tab. Most users have their computer set by default to automatically synchronize with the time.windows.com server.

You can specify another server, to do this, click on the button "Change settings."

In the window that appears, you can click on the button "Update Now" to check the Microsoft time server.

Or select another time server from the drop-down list.

On my computer, the time was not updated automatically because ESET ENDPOINT ANTIVIRUS, bundled with the firewall, is in training mode. So I clicked on the button and created a rule to allow time synchronization. Now the time will synchronize automatically.

Time in an era information technology acquired special meaning For modern man. Each of us looks at our watches at least several times a day. Many people regularly synchronize their time reporting devices through various sources, including the Internet. Accurate time sometimes plays a decisive role in matters where not even minutes, but seconds are important. For example, trading on stock exchanges can result in ruin for a player whose watch shows the wrong time. Let's try to set up ours electronic watch on your computer and synchronize the exact time via the Internet.

Time synchronization technology

First, I’ll tell you a little about the technology used to obtain accurate time from Internet sources. The entire time synchronization process is carried out through a special network protocol called NTP (Network Time Protocol). This protocol is a set of different rules and mathematical algorithms, thanks to which the time on your computer is precisely adjusted with a difference of a few hundredths of one second. There is also a protocol for systems that do not require such precise synchronization, called SNTP. The difference between the source and the receiving device can be up to 1 second.

The technology for transmitting precise time parameters is a multilayer structure, where each underlying layer electronic devices synchronizes with the one above it. The lower the technological layer, the less accurate the time obtained from it will be. But this is in theory, in practice everything depends on many parameters involved in the synchronization system and more accurate time can be obtained, for example, from the fourth layer of devices than from the third.

At the zero level of this transmission chain there are always time reporting devices, roughly speaking, clocks. These clocks are molecular, atomic or quantum time-keeping devices and are called reference clocks. Such devices do not transmit time parameters directly to the Internet; they are usually connected to the primary computer via a high-speed interface with minimal delays. It is these computers that make up the first layer in the technological chain. On the second layer there will be machines that receive time from the first layer of devices through network connection, most often via the Internet. All subsequent layers will receive information about the exact time using the same network protocols from the overlying layers.

Time synchronization in Windows

Let's try to synchronize time using systems Windows XP, Windows 2003 . To do this, click on the clock that is located in your tray (usually in the lower right corner of the screen) to bring up the date and time settings. In this case, be sure to check the settings “ time zone”, which are located there and adjust them if necessary.

For Windows Vista, Windows 7 You can also just click on the clock at the bottom of the screen and go to the settings through the special link “Changing date and time settings”

Then go to the “Internet Time” tab and click the “Change Settings” button.

An Internet time settings window will appear, similar to the same window from Windows XP, 2003.

In this window there is an option to automatically reconcile hours via the Internet, which is available opposite the inscription “ Synchronize with an Internet time server" If you enable it by checking the box, then periodically the time of your computer will be updated via the Internet server by the operating system itself.

Next, opposite the option “ Server:“The user can choose from a list of addresses from which synchronization will be carried out. Try selecting one of them and clicking the “ Update now" If through certain time a synchronization error message will appear below the list, manually enter one of the server addresses below and check the connection to it.

Below is a video that will show the process of setting up the system clock in Windows 7 and synchronizing it.

Changing the automatic time synchronization period in Windows

By default, the Windows operating system accesses synchronization servers only once a week. Provided that the user has set automatic time checking, of course. For some, this period may seem quite long or may be quite frequent than desired. Fortunately, the system allows you to change this parameter through the registry settings.

Open the window Execute” through the menu “ Start" IN command line dial regedit and start with the “ OK" You need to get to the next section one by one

HKEY_LOCAL_MACHINE - SYSTEM - CurrentControlSet - Services - W32Time - TimeProviders - NtpClient

and select the option in the window on the left SpecialPollInterval. The value is given here 604800 , if you convert it to the decimal system. This number of seconds is equal to one week. Here you can enter another value that you need, converting it into seconds.

In addition to the clock running on your computer, there are probably other sources of time that you have to periodically check so as not to get out of the general work schedule or schedule. Clocks can be wall, table, or wrist, and the accuracy of the time shown by them does not always correspond to reality. Meanwhile, trying to synchronize the time of these devices manually, many turn to television sources. However, such means can transmit signals with significant delays, so it is impossible to guarantee accurate time to at least a minute from these sources.

Fortunately, in global network There are many time display services that can help you set your watch to the exact time, down to one second. Of course, the Internet is not blameless in terms of time delays in the transmission of information, but such delays with good communication usually do not amount to more than one second.

Multifunctional service for displaying exact time. In addition to its main purpose, it allows you to check the clocks of different time zones, find out calendar information for the current day, and fine tuning format for displaying time on the screen via the site and display style, display the current year's calendar, find out the time in any city around the world and much more. Perhaps one of the most useful and versatile time services I have ever worked with.

A beautiful image of a dial with moving hands will delight fans of stylish virtual design. In addition to information about the exact time, here you can find data on the time of sunrise and sunset in your region, as well as a link to the weather forecast for the specified city.

There is practically nothing superfluous on the screen, only basic information about the exact time, plus the ability to compare it with the clock of your system. However, there is a small menu with additional functions, such as the remaining time until the end of the world according to the Mayan calendar, a stopwatch, a date converter and a time zone map.

You also have access to other web resources that may help you resolve your issues.

Real-time clock failures in Microsoft operating systems have a long history, dating back to the times of operating systems of the MS-DOS family with a console interface. The first versions of DOS required the user to manually enter the current date and time at system startup and counted minutes and seconds only during the current user session.

The fact is that their readings were not synchronized with time readings on remote servers, as is happening now, but were based on the functioning of a special microchip soldered directly into motherboard computer. Such a concept as a time zone was not supported in principle, and the user himself had to monitor everything related to the operation of the clock in real time. As soon as the microchip battery was discharged, there was no question of any measurement accuracy.

This caused many programs to crash and even systematically freeze the computer. Therefore, the user not only needed to know how the timer mechanisms physically function, but also be able to replace the battery in a timely manner, which required fiddling with the guts of the PC hardware.

However, the time is also lost on modern versions of Windows. Why does the time on the computer get lost when synchronized with remote server and how to fix this problem is a topic for another discussion. It is to her that we have dedicated this short article. We will not deal with the causes of occasional bugs, but will describe a situation where the clock on the computer acts up regularly.

Causes of problems with the system chronometer

There are three main reasons:

There is a discrepancy between the time zone of the region in which the user is located and the time zone specified in the computer settings.
Problems with the CMOS battery, the same one we talked about above. Be that as it may, it is still used by Windows for timer reports.
The computer is infected with a virus special type, affecting the readings of the PC chronometer.

In all these cases, a situation arises that is typical for ancient versions of DOS: the user logs into the system and starts fiddling with the time settings. True, he does this not in the console, but using the tray applet, but the essence of the matter does not change at all. Who enjoys adjusting these parameters every time?

There are also unobvious consequences of this problem. For example, many sites use linking visitors to a certain period of time. And if the readings of the computer clock hands are outside this range, then access to the site’s resources is blocked. Another issue relates to software licensing.

Modern licensed software packages tend to allow the user to work with them only with correctly configured timing that corresponds to the license validity period.

Incorrect operation of the Windows time measurement subsystem leads to the fact that these programs simply refuse to start ( concrete example– antiviruses).

To avoid any troubles, you need to set up synchronization with the Internet. This is quite possible, since most modern computers connected to the network almost constantly:
