This tool enforces strict POSIX cron. See the official spec for more info: POSIX crontab.
- Exactly 5 fields: minute, hour, day of month, month, day of week.
- Valid ranges: minute 0-59; hour 0-23; day of month 1-31; month 1-12; day of week 0-6 (0=Sun).
- Field syntax: * (any), single number, comma list, or numeric low-high range.
- No step values (*/5), no names (JAN, MON), no @daily macros, no Sunday=7.
- DOM vs DOW: If both are restricted (not *), POSIX runs when either matches.
