SSH QuartZ cron Expression

Crontrigger

Crontriggers tend to be more useful than simpletrigger, if you need to base the concept on calendars, rather than simpletrigger a fully specified time interval, recurrence of the launch work schedule.
Crontrigger, you can specify the trigger schedule such as "Every Friday noon", or "every weekday 9:30", or even "every 5 minutes, 9:00 and 10:00 per day, Monday mornings, Wednesday Fridays".
Even so, as with Simpletrigger, Crontrigger owns the starttime specified timesheet when the specified timesheet should stop (optional) end time.
