Hi

I have a time overlap problem on a Dahua (amcrest) NVR which I just noticed. It seems to happen when the clock rolls over to 12AM. Basiaclly, the NVR has continuous recording but I noticed that when I click after 1AM, it jumps back to 12AM area. This tells me there is a time sync problem that somehow at 1AM, the time went back to 12AM and it overwrote some areas.

So I lost footage at 1AM-2AM window even though that window exists.

Does anyone know how to correct this problem on the Dahua NVR and why it is doing this? something to do with time zone adjustment setting? I do have daylight savings time set in NVR but we are in CA and there has not been a daylight savings adjustment recently. We are in the middle of DST zone.
