[Tutor] Could I have used time or datetime modules here?

[Dick Moores]

I'm wondering if my timer3.py could have been written more simply and 
easily by using the time or datetime modules to get the number of seconds 
separating the time now and the time to which the alarm is set.
IOW, is there an easier way to calculate the time difference between the 
time now, say 08:51 and say, tomorrow at 03:45, to take an example of the 
most difficult case?

See timer3.py at

Thanks, tutors.
