Product:Windows Operating System
Event ID:50
Message:The time service detected a time difference of greater than %1 milliseconds for %2 seconds. The time difference might be caused by synchronization with low-accuracy time sources or by suboptimal network conditions. The time service is no longer synchronized and cannot provide the time to other clients or update the system clock. When a valid time stamp is received from a time service provider, the time service will correct itself.

A problem in Microsoft Windows Server 2003 typically causes the Windows Time service (W32Time) to log this error every time the service attempts to synchronize with an external clock.

You might also receive W32Time event log messages 38, 47, and 29 along with this message.

User Action
A supported hotfix to correct this specific problem will be included in the next Windows Server 2003 service pack. For additional information, see article 830092, “W32Time frequently logs Event ID 50 and poor time synchronization occurs on Windows Server 2003” in the Microsoft Knowledge Base.
