To force the W32time service to log an event when the time is adjusted:
1. Use Regedt32 to navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\W32Time\Parameters.
2. Edit or Add Value name Log, a REG_DWORD data type, and set the data value, using the Hex radix, to 0x00000064.
3. Edit or Add Value name WriteLog, a string (REG_SZ) data type, and set the data value to True.
When time is adjusted, the W32time service will post Event ID 61 in the System event log. The text will be similar to The Time service synced time from time source <SOURCE>.
You may also receive Event ID 0, Time set (offset < .5) second.
If an error with synchronization occurs, event ID 11 is posted, The NTP server didn't respond.
