KB - Check database time. NTP offset for database is too large at
Enabled NTP time checks will force your PEM Administrator to use the Network Time Protocol (NTP) to compare the system clock with the network clock. Timestamps are generated on the system so checking to verify if the system has time drift will be reported in the event lock if this setting is enabled. Everything under 5 seconds is not reported, as soon as the system is more than 5 seconds drifted away from the NTP time
In Basic | Server General. You can turn off NTP checks.
