Time ZoneThe server's, unless CRON_TZ is set
Cron checks the schedule once a minute and starts the job at the start of each matching minute, in the server's time zone.
If a run can take longer than the gap between runs, stop runs overlapping with flock: 0 0 * * * flock -n /tmp/job.lock /path/to/job.sh. A second copy then exits straight away instead of piling up.
Cron runs jobs with a minimal environment: use full paths, and send output to a log file (>> /var/log/job.log 2>&1) so errors are not lost.

Questions
How do I run a cron job every day at midnight?
Run crontab -e and add: 0 0 * * * /path/to/job.sh
How do I check the cron job ran?
Look in the job's own log if it writes one, or the system log: grep CRON /var/log/syslog on Debian and Ubuntu, or journalctl -u cron (cron.service is crond on RHEL).
What is the systemd timer equivalent of 0 0 * * *?
OnCalendar=daily in a .timer unit. systemd timers can also catch up on missed runs with Persistent=true.
