PLAYBACK FOLLOWING TIME CHANGES
The DVR uses the time and date to index video on the hard disk so you can find it later.
Changing the time can cause the DVR to work improperly when you try to play back video. If
you set the hour ahead, this is not a problem. But if you set the hour back, there will be more
than one recording at the same time.
Figure 29 shows what happens when you set the hour back from 2 a.m. to 1 a.m., such as
during the fall changeover from Daylight Saving Time. If you try to search for video between
1 a.m. and 2 a.m., the recorder may not operate properly because there will be two hours of
recorded video during this time period. To view video during this overlapping time, you must
start playback before 1 a.m.; then the recorder will play both hours between 1 a.m. and 2 a.m.
