Timestamp

[UlriP]

Is somewhere written down what timestamp time exactly is? Is it time of start of the exposure? Is it time of the middle of the exposure? Or is it end of the exposure or even time of when software write photo on drive? We are using indi-allsky for scientific researh of meteors and with more stations on diferent software far apart we need to know that.

Allso, can I change timestamp from computer time? I tried to include time zone with :Z and :z to time stamp without any succsec. I would like to change it to UT. I know I can change system clock to UT, but as we are in UT+1 and we use day light saving, it's easier to work with our local time to see if is something wrong.

The datestamp of images in the database are recorded at the end of the exposure. The datestamps are also recorded in the local timezone of the system. indi-allsky expects time to be in the local timezone.

If you want to change the system time to UTC, but keep the local time in indi-allsky, I think you can just set the TZ environment variable for the indi-allsky systemd unit in /etc/indi-allsky/indi-allsky.env. I have not tested this, but it should work in theory.
