Time not synchronized

What to do if the time on the Pi-Hole is incorrect?

pc time is 18:07 and pi-hole time is 17:07
What could be the problem? And what else can I try?

Thank you!

There are multiple reasons, for one, it could be that the timezone on your Pi-hole is incorrect. Another issue can be that some form of "tracking protection" is enabled in your browser, and, hence, the timezone information given to the user interface is incorrect - rendering the shown time incorrect. Which browser are you using?

If it is Firefox, unticking this box should help:

If the issue remains, the timezone on the Pi-hole could still be wrong.

You didn't post a debug token or any details about your installation, so we need to guess some things.

Are you running Pi-hole in a docker container?

no docker pure raspberry pi with debian

Your timedatectl output shows your PC in CET time while the RTC is in UTC time. CET is 1hr different from UTC time, hence the difference ( note the RTC in local time is set to no in your timedatectl )

something doesn't fit

Your local time is correct on the machine running Pi-hole, how about my suggestion about the tracking protection further up in my answer?

protection is deactivated

Is the user using a VPN, and if so, in a different location than local residence, since this will throw off the timing as well, it is the reason I disable Pi-holes NTP, myself.

Another possible reason is that the clock is wrong on the machine you are running your browser on. It may be set to UTC and then set to your local German time which would be wrong.

What is the output of

timedatectl

on your local computer where you are using Firefox?

Unfortunately you were right, it was a problem with Librewolf. The time is now synchronized, everything is fine, thank you for your effort.
