When using NTP, the server first verifies that the specified servers are legitimate; then, over a period of a few hours, gradually adjusts its clock to the time provided by the NTP server. This gradual adjustment is normal, and is designed to minimize the effects of changing the server’s clock on utilities that use file timestamps.

If the time initially set on the storage server differs from the time returned by the NTP servers by more than 15 minutes, the server does not try to synchronize to the NTP time; instead, it records a Warning event in the event log, indicating that the date and time must be manually changed to within 15 minutes of the NTP time.
