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.
|Local time||12:00 AM||1:00 AM||2:00 AM = 3:00 AM||4:00 AM||5:00 AM|
|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.
