• Set the time zone to GMT or Coordinated Universal Time.
• Do not enable seasonal time adjustments such as daylight savings time.
• Before installing IMC, check that the system time, date, and time zone settings on the server are
correct.
After IMC is started, do not modify the system time of the server; otherwise, intermittent problems can
occur such as:
• When jumping to a future time, the system can take a long time to process a large amount of data.
It can exceed the maximum time that the data can be saved in the database.
This affects the current data sampling speed and results in delay. After the processing of such data
is complete, the delay is gradually recovered.
• When you modify the system time to a past time, data with overlapping time can occur, and data
processing might become abnormal. After the overlapping time is past, data processing becomes
normal again.
