Timezone support for mute timings

[armandgrillet]

What means "Monday" if I'm based in Sidney? It means that I will not have alerts muted during my Monday morning.

On the engineering side, mute timings are taken care of by the alertmanager within Grafana which is based on the Prometheus Alertmanager and it also doesn't have this feature.

Have you verified that your TZ environment variable is set correctly? (if you are using a hosted instance)

Disclaimer: I have no knowledge of grafana's code and cannot asses if it might be a bug on their side 💁‍♂️

Then again, trying it myself - I do see some issues with it:

dc exec grafana date
Sat May  7 00:46:49 CEST 2022

And tried a mute timing from 0:00-6:00 - and was awoken at 0:15 😓

Then I had to fiddle my way around dubious UI error Snackbars "Error: Bad request data" (which meant to tell me that 00:00 wasn't valid as end time - granted, I should've known this, but the error wasn't telling me in which section of the settings I have an error, so it took me a while :/ )

... I will write again >= tomorrow night if that wasn't my issue

Same problem here. I have a mute timing from 00:00 to 07:00. Under Preferences, timezone is set to America/Sao_Paulo (UTC-3).

However, I start receiving alerts daily at 4:00.

Right now I'll change the mute timings to take the timezone into account, but it would be great to have this feature.

This feature would be nice to have. Especially when DST kicks in.

This has been done in alertmanager with prometheus/alertmanager#2782.

Porting should be possible.

This would be nice to have to handle DST. As a workaround currently, I'm expanding the range so that my desired range will always be covered, just with one extra hour on either the front or back depending on DST.
Example: For midnight through two in CST, midnight would be 06:00 UTC and two would be 08:00 UTC. In CDT, they are 05:00 UTC and 07:00 UST. So the time I end up setting is 05:00 UTC - 08:00 UTC. This translates to 23:00-02:00 CST and 00:00-03:00 CDT, which covers my desired range of 00:00-02:00 in both CST and CDT. However, it would be much more convenient to just be able to use time zones.

This would welcomed as a new feature.
