Annual time changes to or from Daylight Saving Time (DST) can affect the way video archives are viewed and queried in Security Center.

Time changes do not prevent your cameras from recording video data. The Archiver always records using Coordinated Universal Time (UTC), which does not timeshift for DST, and archive queries are always sent to the server with UTC timestamps.

Using UTC isolates video archives from the effects of time changes. However, because Security Desk and Config Tool can be configured to use, and display, a time zone other than UTC, side effects can be observed when time is adjusted backward or forward.
NOTE: The Eastern Standard Time (EST) time zone is used as an example, however this applies to all time zones that are subject to DST.
