Daylight Saving Time (DST)

The unit is embedding world DST rules, and it is always enabled.

DST vs. Location

DST rule totally depends on your location.

Please, set correct GMT/Location in “Service: DateTime” menu.

“Service: DateTime” means DateTime menu in Service menu.

Effects of daylight

Time returns to one hour later at the end of DST, this means one hour recording

data has the same time stamp. The overlapped zone (B) could be handled optionally.

Refer to each menu descriptions in Chap 3. and Chap 4.

▪ Playback : The unit playback zone (A) and zone (B) are both continuously.

▪ Calendar Search : You can address exact time point in zone (B).

▪ Event Search : You can limit search range to zone (B).

▪ Backup : You can limit backup range to zone (B).

Updating DST rule

Once your location’s DST rule is changed, then you need to upgrade firmware.

Otherwise, the last DST rule or no rule will be applied.

If you cannot upgrade firmware, we recommend to do followings;

▪ Backup : Do backup prior to adjusting system clock backward.

Otherwise, the overlapped data (zone (B)) will be destroyed.

▪ Clock adjustment : Adjust system clock in Service::DateTime menu.
