[BUG] - switch from daylight saving time to standard time causes problem

[arigon]

Describe the bug

I am running a job on 00:01 every day. Today was the switch from daylight saving time to standard time in Europe. The job did run one hour too early at 23:01.
Update: And I just realized the job was executed twice.

To Reproduce

_, err := s.Every(1).Day().At("00:01").Do(reports.RunDailyReport)

Version

0.3.1

Expected behavior

It should not run at 23:01. It should only run once.

Thanks for the report @arigon. Will take a look at it.

What time zone are you using? I'm wondering if it's set to UTC and was the same but then got off by an hour when your time changed?

[arigon]

I am using Europe/Berlin which is my time zone, otherwise it wouldn't start at 00:01 as expected. By the way, it hasn't started at 00:01 now either. I am now wondering if it will work Tuesday at 00:01.

[arigon]

Okay.. The job did just run, at 23:01.. How can I switch it back to 00:01?

[Streppel]

This is unfortunate, I'm sorry. I believe I've already found what's up and will make a commit soon. Meanwhile, can you try to restart your worker application? I know this is not ideal, but hopefully it'll work while we don't merge a fix.

[arigon]

I already restarted that container yesterday. But I will do so again.

after intensive research with @Streppel (thx a lot!) we found the problem is in the alpine docker image which didn't update properly from CEST to CET. I will close this :)
