Event ID 31 — Local Time Zone Configuration

  • Article

Applies To: Windows Server 2008

The Windows Time service (W32time) applies the local time zone configuration. Windows Time Service uses Coordinated Universal Time (UTC), which is based on an atomic time scale and therefore independent of time zones. Time zone information is stored in the computer's registry and added to the system time just before it is displayed to the user.

Event Details

Product: Windows Operating System
ID: 31
Source: Microsoft-Windows-Time-Service
Version: 6.0
Symbolic Name: MSG_TIME_ZONE_FIXED
Message: The time service discovered that the system time zone information was corrupted. Because many system components require valid time zone information, the time service has reset the system time zone to GMT. Use the Date and Time in Control Panel to set the correct time zone.
