Tasks are not started according to local/given timezone

[rleins]

Steps to reproduce:

1. Schedule a task for every day
2. Define timezone options inside the task:
   option location = timezone.location(name: "Europe/Berlin")

Expected behavior:
I expect the task started at midnight of the given timezone (in my case local timezone).

Actual behavior:
The task start at midnight UTC, which is currently (CEST) two hours off.
Every range or other timezone-related query data are correct, so it's only the starting time.

Environment info:
Docker image with correctly set timezone

I have further investigated this point.

If I set the timemask via cron, then only the first start of the task starts in Zulu time. Any next start is correct in local time.
It seems the parsing of the location-option is one step too late...

But every server restart or task re-save makes a new wrong start-time...

Furthermore it would be very nice if one could set a global location-option. So that any timezone-related operation (like tasks or functions) works with the correct timezone... No one lives in the zulu timezone 🙂
