[Support]: Frigate 0.14 support for 30 minute offset timezones (e.g. UTC + 5.30)

[rajil]

Describe the problem you are having

Hello,

There are a bunch of time zones which have an offset from UTC (listed here) . Unfortunately frigate review/recording is not showing up for an offset time zone.

My setup is as follows:

Docker host on the server is set to UTC,

$ sudo timedatectl status
               Local time: Mon 2024-05-20 12:35:27 UTC
           Universal time: Mon 2024-05-20 12:35:27 UTC
                 RTC time: n/a
                Time zone: Etc/UTC (UTC, +0000)
System clock synchronized: yes
              NTP service: inactive
          RTC in local TZ: no

Frigate browser on my desktop is set to IST,

$ timedatectl status
               Local time: Mon 2024-05-20 18:06:21 IST
           Universal time: Mon 2024-05-20 12:36:21 UTC
                 RTC time: Mon 2024-05-20 12:36:21
                Time zone: Asia/Kolkata (IST, +0530)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

Problem

When i goto to review my alerts, it plays the preview of the camera event taken at 4:50 PM. Here is a partial screenshot of the preview/thumbnail

When i click on the thumbnail, it opens the recording and shows an error message, "No recordings found for this time". A partial screenshot is shown below:

Temporary Workaround

If i change my desktop/browser to UTC, the recording plays fine.

[desktop] # timedatectl set-timezone UTC
[desktop] # timedatectl status
               Local time: Mon 2024-05-20 12:42:18 UTC
           Universal time: Mon 2024-05-20 12:42:18 UTC
                 RTC time: Mon 2024-05-20 12:42:18
                Time zone: UTC (UTC, +0000)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

The preview/thumbnail is at UTC time now,

Clicking on the thumbnail, recording opens up and plays successfully. Here is a screenshot from the recording showing the camera time.

Should be improved by #11444

[rajil]

I updated to dev-6e39d55 and can confirm that the 4:50pm recording now plays as expected. However the recording for the next event at 5:15 PM does not play. The preview video plays fine, but the recording shows a message "No recordings found for this time". The timeline is stuck at,

None of the recordings between 5:00 to 5:30 PM play, but the recordings from 5:30 to 6:00 pm play fine. I suspect the updated logic doesnt work for the first 30 minutes past the hour.

[NickM-27]

should be fixed in #11449

[rajil]

I updated to dev-7413810 and that seems to have fixed all the issues on Chrome (Linux).

However, i am still seeing issues on Firefox (Linux). The preview for an event at 6:18PM plays fine. However, if i try to view its recording the timeline jumps to show the event at 6:30pm. If i then change to Events view and click on the 6:18pm thumbnail, i get "No recordings found for this time". I captured the following screenshot from Chrome to show the exact time,

So it seems that Chrome is fixed but there is still issue in firefox.

I did some further testing with Chrome.
Event at 07:58 PM plays
Event at 08:17PM doesnt play
Event at 08:31PM doesnt play

Here is a screenshot from Chrome,
