Setting the system time
As a best practice, configure the following settings:
Set the time zone to GMT or Coordinated Universal Time.
Do not enable seasonal time adjustments such as daylight savings time.
Before installing IMC, verify that the system time, date, and time zone settings on the server are correct.
Do not modify the system time on the server after IMC is started. If you modify the system time, the following issues might occur:
When jumping to a future time, the system might get so occupied in processing the sudden burst of expired data that realtime data sampling will be delayed. The delay is automatically recovered after the processing of expired data is complete.
When you modify the system time to a past time, data with overlapping time occurs, and data processing might become abnormal. After the overlapping time is past, data processing becomes normal again.
