Why sometimes time sync issue occurs on server 2008 and we need to force the synhronization.
Error:The time service has not synchronized the system time for 86400 seconds because
none of the time service providers provided a usable time stamp. The time
service will not update the local system time until it is able to synchronize
with a time source. If the local system is configured to act as a time server
for clients, it will stop advertising as a time source to clients. The time
service will continue to retry and sync time with its time sources. Check system
event log for other W32time events for more details. Run 'w32tm /resync' to
force an instant time synchronization.
