how to cancel the schedule event

[yidingdian]

Hi, I use later to trigger my events,

var sched = later.parse.recur().on(new Date(event.starttime)).fullDate(),
      t = later.setTimeout(function, sched)

I know calling clear would cancel the event t.clear()

Now I met a problem. I had many specific times to schedule, such as ‘ 2017-02-17T03:05:23Z, 2017-02-17T07:05:23Z, 2017-02-18T04:05:23Z ... ’ then there was a request to cancel one of the schedules, '2017-02-17T07:05:23Z'. I couldn't get the instance 't', how could I cancel the event?

Thanks in advance for your help!

I had use 'agenda' replace 'later' to resolve that.
