Scheduler clock isn't syncron to the ticket time (time zone problem?)

[Trenga]

Hello community

Infos:

• Used Zammad version: 3.3.x
• Used Zammad installation source: package
• Operating system: Debian 9.8
• Browser + version: Firefox 64 actual

Expected behavior

• Synchron time between ticket time and scheduler

Actual behavior:

• Operation System time is correct.
  The creation time of time is correct.
  But if I setup a task in the “Scheduler”
  is the “Scheduled Time” always 2h later as adjusted time.
  And the performing is also 2h later.

Steps to reproduce the behavior:

• I tested a lot but can’t find any solution to fix the time Zone Problem of the scheduler Clock.

Please see the attached Information:

Scheduler runs in UTC and does not respect the timezone setting.
