Time service has 86,400 seconds not synchronized with system time what do you mean?

Sometimes you find that there are some sources in the Win2003 system log: W32Time, the event ID is: 36, the event is described as:

The time service has 86,400 seconds that are not synchronized with the system time because no time service provider provides an available timestamp. The time service will no longer be synchronized, nor can it provide time for other clients or update the system clock. Check the system events shown in Event Viewer to confirm that no more serious problems have occurred.

This is a warning event. Although it does not have much impact on the use of the system, why is the system default update cycle different from event log reports? It was also very disturbing to see such a warning, Huang. In fact, the time synchronization update frequency for the WinXP and Win2003 systems defaults to 7 days, which is normal for the WinXP system, but it seems a bit long for server systems that require a relatively high time accuracy, and, in addition, The Huang number that always reports this warning every other day is also annoying. So for the Win2003 system, you can try to set the time synchronization interval smaller, such as a day, so that the time accuracy is higher while also reducing the number of system log reports.
