When time is adjusted forward, it changes from EST to DST.

Before 2:00 AM, Security Center uses the EST (UTC-5), while starting from 2:00 AM, it uses the DST (UTC-4), as illustrated below.
  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
Due to the time being adjusted forward, the following behaviors can be observed when playing back or exporting archives:
  • The time jumps forward by one hour in the timeline. Instead of showing 2:00 AM, it shows 3:00 AM.
  • There are no archives to export between 2:00 AM and 3:00 AM, because this period corresponds to 7:00 AM UTC.
If you do not want to see the time jumping forward by one hour during video playback, you must configure Security Desk to use UTC.
