Questions fréquentes

Which cron dialect?

Standard 5-field Unix cron (minute, hour, day-of-month, month, day-of-week) with common extensions: */n step values, ranges (1-5), lists (1,3,5).

Does it support seconds or years?

Not yet - those are Quartz-scheduler extensions. Standard Unix cron and most Linux crontabs use 5 fields.

How does it handle timezones?

Next-run previews use your browser's local timezone. Remember: your server's crontab uses the server's timezone unless overridden.

What's the difference between * and ?

In standard Unix cron there is no ? - use *. The ? character is Quartz-specific for disambiguating day-of-month vs day-of-week.
