Set the time on the client PC (the PC on which the browser is running). Be careful when changing the time.

If you reset the time on the server PC, and the time of data saved by logger actions or alarm actions is reset halfway to a past time, inconsistencies may occur when displaying trends, alarms, or creating Daily/Monthly/Yearly Report.

Therefore, for logger actions and alarm actions, set the process to "correct to the last saved time and save" (or "do not save data") when the PC clock is reset.
