Hello Checkmk Forum! I am hoping I just managed to miss this topic somewhere in the forums. We have our TZ set to TZ=America/New_York in $OMD_ROOT/etc/environment but are noticing a major discrepancy within the Checkmk interface we use. Even with the TZ set the way it is we are seeing a difference of hours with reporting alarms and graphs. Real time graphs seem to show the correct time. We have scoured the internal settings of the interface and cannot find a place to change or adjust this.
Any help is greatly appreciated.
Screenshot was taken at 11:41EST. Alerts happened 4 hours & 47 minutes ago at 06:54 EST. The offset is easy to calculate but when troubleshooting it can lead to confusion and extended troubleshooting times
You need to set the correct timezone inside the OS itself.
What do you see with this command inside Ubuntu?
timedatectl --all
Local time: Tue 2025-03-04 19:06:14 CET
Universal time: Tue 2025-03-04 18:06:14 UTC
RTC time: n/a
Time zone: Europe/Berlin (CET, +0100)
System clock synchronized: yes
NTP service: inactive
RTC in local TZ: no
timedatectl --all
Local time: Tue 2025-03-04 20:21:12 UTC
Universal time: Tue 2025-03-04 20:21:12 UTC
RTC time: Tue 2025-03-04 20:21:12

We are fixing that now and will see how things change
