Calling Quartz Scheduler In Non Periodic Time Interval
===

In quartz scheduler I have a doubt

**For example**

  If we schedule job for every 5 minutes or 10 minutes or 2 hours it is ok we call scheduler using regular time interval like below no problem,
  
        SimpleTrigger simpleTrigger = new SimpleTrigger("mytrigger",sched.DEFAULT_GROUP,new Date(),null,SimpleTrigger.REPEAT_INDEFINITELY,30L*5000L);


  But,If I schedule job @ 2'0 clock and 3'0 clock today then,tommorow I change it to  5'0 clock and 7'0 clock and 11'0 clock, my doubt is if fixed interval we call it in above way but it not fixed or periodic interval how do we handle it.
