Event scheduling past next 24 hours

As it stands the scheduling library is highly alarm focused.

Would it make sense to extend it to encompass the scheduling of events with absolute timestamps?

Potential benefits:

1. Countdown timers would gain the ability to schedule more than 24 hours out and accurate negative time.
   
2. Persistent stopwatches.
   
3. Syncing of calendar events.
   
4. Place for apps to push events such as sunrise and sunset.
