AD410 resetting the TIme Zone

[Revo2Maxx]

So anyone having this issue? I went to play back something tonight about 315am, When i started to play it back I noticed it was playing back from an area on the time line that didn't have any mark of being recorded to. Then i noticed the time was off an hour. So I let it playback until I seen what I needed, then went to the SH App and found that my cameras time zone was at Choose a Time Zone. So I picked the zone and turned on DST and seen the camera show the right time in my NVR.. Now I need to find out how long it takes before it goes back to this. Oddly I am getting event notices still so that is good. Yet don't like the idea of the reset.
