Hi @fabrei, thanks for your PR.

Your update seems to have some points not covered by the unit test. Can you add tests?

Hi @masayuki038,

I added some tests. Hope it works now with test coverage :)

Ah, damn the timezone O_o

The prometheus query runner does not use any timezone while calculating start and end time. It uses the local timezone on the system. In the CI it is UTC, which differs from my local one.

Now the testcases should be fixed.

@fabrei Thanks for your updates! It is very helpful.
Looks good from my end. Please wait for a few days.

@guidopetri @konnectr Could you check this if you have some time?
