All exacqVision video is timestamped in UTC, so there is no ambiguity as to the absolute time when the video was recorded. When exporting video, the time zone of the system on which the video was recorded is not stored. Starting with exacqVision version 3.4, two features were added to make this more transparent to the operators:
<br>
- In exacqVision Client, an onscreen display shows the server time zone (in offset from UTC) along with the timestamp. If this option is not configured for the camera, the timestamp is shown in the client’s local time.
- In ePlayer, the timestamp of the recorded video is shown in the time zone of the local computer on which it is playing, but the time zone offset is shown. Thus, if you watch a video on a computer set to EDT, you might see 2:00 (GMT-4:00), whereas the same video viewed on a computer in CDT would show 1:00 (GMT-5:00). The UTC timestamp is the same in both cases. Knowledge of the physical location of the recording server, which is clearly needed for evidentiary purposes, can correlate the local time of the machine on which the video is being watched to the local time of the server on which it was recorded.
