How is the Time Delta Tolerance Determined?

The delta tolerance is equal to the round trip time, with 0.5 seconds as the minimum delta. The synchronization interval is 15 minutes (900 seconds), as defined by the TimeSyncUpdtItrvl Config.ini [SYSTEM] section variable.

If the time delta is 1 second, then the client’s clock is slewed by 10 milliseconds every second. The client will then be in sync after 100 seconds, but any logs done on time won’t show any visible discontinuity. The client’s clock will immediately be adjusted if the delta exceeds 5 seconds.
