Cross-system syntax variants

Same intent, different schedulers. Use this table when migrating between systems.

System	Expression	Note
Standard cron (POSIX)	0 12 * * *	minute=0, hour=12 (24-hour)
Jenkins	H 12 * * *	spread minute across executors
Quartz (Java)	0 0 12 * * ?	6-field
systemd timer	OnCalendar=12:00	fires at 12:00:00
AWS EventBridge	cron(0 12 * * ? *)	noon UTC — for noon LOCAL set the schedule's TZ

Common pitfalls

12 in cron is ALWAYS 12:00 (noon) — there's no 12 PM/AM ambiguity. But humans often mean midnight when they say '12 o'clock'. Clarify in code review.
Containers default to UTC. Noon UTC = different wallclock for users in NY (07:00) vs Tokyo (21:00). Convert per audience.
If you also have a 12:00 user-facing event (lunch reminder), competing crons at the same exact second cause race conditions.
