When time is adjusted forward, it changes from Eastern Standard Time (EST) to Daylight Saving Time (DST).

The timeshift from EST to DST occurs at 2:00 am. Before 2:00 am, Security Center uses the EST (UTC-5). Starting from 2:00 am, it uses the DST (UTC-4), as shown in the following table:
  EST Time change DST
Local time 12:00 am 1:00 am 2:00 am = 3:00 am 4:00 am 5:00 am
Offset (hours) -5 -5 -4 -4 -4
UTC 5:00 am 6:00 am 7:00 am 8:00 am 9:00 am
Because the time was adjusted forward, the following behaviors can be observed when playing back video or exporting archives:
  • The time shifts forward by one hour in the timeline. At 1:59:59 am, the displayed time advances to 3:00 am.
  • There are no archives to export between 2:00 am and 3:00 am, because this period was skipped.
To prevent the time from shifting forward by one hour during video playback, you must configure Security Desk to use UTC.
