SLAs broken? Escalations outside of business hours and after first response met

  • Used Zammad version: 7.1.3-1787900513.d20f98a.ubuntu24
  • Used Zammad installation type: Source
  • Operating system: Ubuntu Server 24
  • Browser + version: Chrome Latest

Expected behavior:

SLAs to work as specified - SLAs and Escalations | Zammad Features

Actual behavior:

Escalations happening outside of define business hours.

Tickets escalated due to missed first response, even though agent has replied to the ticket well before the deadline.

Steps to reproduce the behavior:

Just using the system.

We had an issue with reports caused by the Europe/London timezone not being recognised - Could this be related?
