    I am running XP and notice that my pc is regularly 10 minutes fast. I have adjusted the system clock but the next day the same thing happens.
    I have now downloaded atomic.exe and used this to sync but the time remains unchanged despite the program telling me
    Obviously my wrist clock could be fast but I did check that against other sources, so the question remains why does my computer think the time is 10 minutes ahead of the actual time?

    Hi, how old is your computer? Beacause inside is a round Lithium battery (the size of ring)

    These keep the time of the system, and if your batery is dieing (expected life of 5years) that'll be why and it will need replacing...

    First thing you should do is go to BIOS and set up correct date and time.
    Save and exit BIOS go into Windows and shut down the PC.

    Disconnect the Power cable from teh PC and leave it disconnected for 10 minutes.

    Plug it back in and go to BIOS again.
    Check the BIOS time. If it's not the correct time do what dj-jamster said and replace the battery(it's cheap and you can find one at your local computer store).
    If the time is still correct then the battery is ok and your problem is with the operating system.

    So if it's not battery you have 2 posibilities:

    1. To configure Windows Time to sync with hardware clock (the one in the BIOS)
    2. To configure Windows Time to sync with external clock (Internet)

    1. To configure Windows Time to sync with hardware clock


    1. Click Start, click Run, type regedit, and then click OK.
    2. Locate and then click the following registry subkey:HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
    3. In the right pane, right-click ReliableTimeSource, and then click Modify.
    4. In Edit DWORD Value, type 1 in the Value data box, and then click OK.
    5. Locate and then click the following registry subkey:HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
    6. In the right pane, right-click LocalNTP, and then click Modify.
    7. In Edit DWORD Value, type 1 in the Value data box, and then click OK.
    8. Quit Registry Editor.
    9. At the command prompt, type the following command to restart the Windows Time service, and then press ENTER:net stop w32time && net start w32time
    10. Run the following command on all the computers other than the Time Server to reset the local computer's time against the Time Server: w32tm -s
    2. To configure Windows Time to sync with external clock (Internet you can use the Microsoft time server (time.windows.com) ):


    1. Click Start, click Run, type regedit, and then click OK.
    2. Follow these steps to change the server type to NTP:
      1. Locate and then click the following registry subkey:HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
      2. In the right pane, right-click TYPE, and then click Modify.
      3. In Edit Value, type NTP in the Value data box, and then click OK.
    3. Follow these steps to configure the server as a reliable time source:
      1. In the right pane, right-click ReliableTimeSource, and then click Modify.
      2. In Edit DWORD Value, type 1 in the Value data box, and then click OK.
    4. Follow these steps to configure the server LocalNTP to 0:
      1. In the right pane, right-click LocalNTP, and then click Modify.
      2. In Edit DWORD Value, type 0 in the Value data box, and then click OK.
    5. Follow these steps to specify the time sources:
      1. In the right pane, right-click NtpServer, and then click Modify.
      2. In Edit Value, type Peers in the Value data box, and then click OK.

        Note Peers is a placeholder for a space-delimited list of peers from which your computer obtains time stamps. Each DNS name that is listed must be unique.
    6. For Windows 2000 Service Pack 4 only, set the time correction setting. To do this, follow these steps:
      1. Locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
      2. In the right pane, right-click MaxAllowedClockErrInSecs, and then click Modify.
      3. In Edit DWORD Value, type TimeInSeconds in the Value data box, and then click OK.

        Note TimeInSeconds is a placeholder for the max number of seconds difference between the local clock and the time received from the NTP server in order to be considered a valid new time.
    7. Follow these steps to set the poll interval:
      1. Locate and then click the following registry subkey:HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
      2. In the right pane, right-click Period, and then click Modify.
      3. In Edit DWORD Value, type 24 in the Value data box, and then click OK.
    8. On the File menu, click Exit to exit Registry Editor.
    9. At the command prompt, type the following command to restart the Windows Time service, and then press ENTER: net stop w32time && net start w32time
    10. Run the following command on all the computers other than the Time Server to reset the local computer's time against the Time Server: w32tm -s
    The HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Period registry key controls how frequently the Windows Time service synchronizes. If a value is specified, it must be one of the special values in the following list:
    • 65531, "DailySpecialSkew" - Sets synchronization to one time every 45 minutes until successful one time, then one time every day.
    • 65532, "SpecialSkew" - Sets synchronization to one time every 45 minutes until successful three times, then one time every eight hours. This is the default setting.
    • 65533, "Weekly" - Sets synchronization to one time every seven days.
    • 65534, "Tridaily" - Sets synchronization to one time every three days.
    • 65535, "BiDaily" - Sets synchronization to one time every two days.
    • 0 - For NT5DS, the synchronization is one time every 45 minutes until successful three times, then one time every eight hours. For NTP, the synchronization is one time every 8 hours.
    • freq - freq stands for the number of times per day you want Windows Time service to synchronize. If want to use a value other than any one of those specified earlier, you must use this option.
