Do these queries appear right when you restart the Pi-hole? It may be that the system starts logging before it gets the correct time (because Pis don't start up knowing the time already).
When i look at current pihole.log i see logging with correct timestamp.
When i go in the UI and select Query Log and the "Show all", then I only see logentries with 2018-11-24 date, but different times. The total number of entries stay the same on a life system, that is weird too, right?
(yesterday I tried to repair with both pihole -r repair and after that reconfigure, both didnt solve the problem)
I installed another pihole on my home server with Docker, so this issue can be closed.
We use system functions to translate dnsmasq's log timestamps (e.g. Mar 3 00:00:38) to Unix timestamps. Apparently, something is severely broken somewhere on your system?
But as I said, i setup a new instance on different hardware, so for me the issue can be closed.
I leave the rpi setup running in case you guys want to investigate this further.
(Although I can imagine there are more pressing matters to attend to )
Thanks for the quick responses and keep up the good workt, i am a huge fan!
