sudo journalctl -u cron | grep "scriptname"
It will show you when they were executed (and what user):

# Run by misskey user
Sep 17 20:30:01 slippy CRON[389091]: (misskey) CMD (/home/misskey/kiki fetch && /home/misskey/kiki publish)
# Run by root (creates daily mysql dumps)
Sep 17 01:00:01 slippy CRON[246758]: (root) CMD (/root/backup/backup.database.mysql.sh)
# Run by root (creates weekly basebackup for WAL)
Sep 17 02:00:01 slippy CRON[252575]: (root) CMD (/root/backup/backup.database.postgresql.sh)
# Run by my own user to clean up old remote files through API calls.
Sep 17 03:00:01 slippy CRON[258304]: (efertone) CMD (/home/efertone/slippy-maintenance/clean-old-remote-files.py)
It will not record the exist status, but I get an email always when stderr is not empty.

Hope it helps.
