FAQ

Which cron flavor is supported?
Standard 5-field cron (minute hour day-of-month month day-of-week). Step (*/n), range (a-b) and list (a,b,c) syntax are supported.
What about seconds or @yearly aliases?
6-field (with seconds) and aliases like @yearly are not supported yet — they are on the roadmap.
