But, a "hack" would be..... 1,11,21,31,41,51 * * * * /usr/bin/date +%Y-%m-%d\ %H:%M:%S > /tmp/mydate 0,10,20,30,50,50 * * * * journalctl --since="`cat /tmp/mydate`" | mailx "Journalctl for last 10 mins" user" There probably is a better way to get a timestamp from 10 minutes ago..... And I can't now wrap my head around the "relative times" part of the man page.
