After upgrading to 2.332.1 using the new journal logging, There are TWO time stamps in every line of the log. Example:

Mar 27 17:57:16 redacted.host jenkins[1663366]: 2022-03-27 15:57:16.168+0000 [id=149]        INFO        hudson.model.AsyncPeriodicWork#lambda$doRun$1: Started Periodic background build discarder

The first time stamp is from jounal logging and the second from jenkin's logging. I suggest to remove the second one. The various time-based filters of journalctl use the first one anyway so the second one is quite useless now. Note: the time difference in the above example is caused by the the difference of CEST (localtime, used in journalctl) vs. UTC (used by jenkins logging).
