Possible Causes

Solution 1

Manually synchronize system time.

1. Click Change date and time settings in the lower right corner of the desktop. The Date and Time window is displayed.

5. Check whether system time is consistent with the local standard time.

Solution 2

Change the update frequency of system time by editing the Windows registry.

1. In the Run dialog box, enter regedit to access the registry editor.
2. Choose HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > W32Time > TimeProviders > NtpClient and double-click SpecialPollInterval.
3. In the dialog box that is displayed, set Base to Decimal.
4. Set the time synchronization interval.

   The value displayed in Value data is the interval (in seconds) for automatic time synchronization. Set this parameter as required.
