Timestamp are not correct

Infos:

• Used Zammad version: 6.1
• Used Zammad installation type: package
• Operating system: debian 12
• Browser + version: any

Expected behavior:

• The local time should accurately reflect the current time for the specified timezone.

Actual behavior:

• The local time in the whole system is incorrect, showing two hours in the past from the true local time. In the postgre db is also the wrong timestamp.

Steps to reproduce the behavior:

• I Installed a fresh zammad 6.1 in debian 12 and restore it from an zammad 6.1 from debian 10
