## Observation
There were many logs for `check whether clocks on the local host and the web UI host are in sync`.
Openqa seems unavailable for ~10min

chrony status looks ok on OSD.
I saw also a python3 update and then issues with telegraf but I dont think they are related with OSD.
## Steps to reproduce
Find jobs referencing this ticket with the help of
https://raw.githubusercontent.com/os-autoinst/scripts/master/openqa-query-for-job-label ,
call `openqa-query-for-job-label poo#162038`
## Suggestions
* Consider outputting the actual "mismatch" value (the time delta exceeding some threshold) in the log message if possible and not hidden in a hashsum (https://github.com/os-autoinst/openQA/blob/master/lib/OpenQA/Shared/Controller/Auth.pm#L162)
* Find out/fix why some jobs fail without a specific error besides "api failure" besides showing timestamp errors in logs
* Crosscheck with #163592 if the symptoms actually still appear
* Try to simulate slow response times (by putting a sleep at the right place) to reproduce the issue (How slow can we go before "timestamp mismatch" becomes an issue?)
* If the real cause for the error message is actually not a time difference but too slow responses by the web UI extend the error message accordingly
## Out of scope
* Add details to bare "api failure" #163781
