Schedule with a termination condition

[bekaiser]

There is a schedule feature which allows triggering on a schedule.

I am looking for this functionality until a certain datetime.

and for following steps to have access to the datetime and to perform date math with it.

for example if a following step wants the number of days til termination, or number of remaining emails.

would be useful for:

trip to Redmond in N days

password expires in N days
