FAQ
Which cron syntax is supported?
Standard 5-field crontab: wildcards, lists, ranges, steps (such as */10 or 0-30/5), month and weekday names, plus @hourly, @daily, @weekly, @monthly and @yearly aliases.
Why exactly 5 fields?
Crontab uses minute, hour, day of month, month and day of week. Six-field expressions with seconds and Quartz extensions such as ? or # are not supported.
Which time zone is used?
Your browser's local time zone. The current zone is shown with the results, and daylight saving changes are handled by the browser.
