SUMMARY

This article describes how to force the W32time service to log an event in the event log when the time has been adjusted.

MORE INFORMATION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To enable logging for W32time, use Registry Editor to add the following registry values:
Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\W32Time\Parameters
Value name: Log
Data type: REG_DWORD
Value: 0x00000064 (Hex)

Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\W32Time\Parameters
Value name: WriteLog
Data type: REG_SZ
Value: True
After you make these changes, you must stop and restart the W32time service.

When the time is adjusted, event ID 61 is logged in the System log. The text for this event is similar to:
The Time service synced time from time source (SOURCE)
This is followed by event ID 0:
Time set (offset < .5) second
If an error with synchronization occurs, event ID 11 is logged:
The NTP server didn't respond
