What is the simplest way to find the difference between 2 times in python?

I have 2 time values which have the type datetime.time. I want to find their difference. The obvious thing to do is t1 - t2, but this doesn't work. It works for objects of type datetime.datetime but not for datetime.time. So what is the best way to do this?

Answer

Firstly, note that a datetime.time is a time of day, independent of a given day, and so the different between any two datetime.time values is going to be less than 24 hours.

One approach is to convert both datetime.time values into comparable values (such as milliseconds), and find the difference.

t1, t2 = datetime.time(...), datetime.time(...)

t1_ms = (t1.hour*60*60 + t1.minute*60 + t1.second)*1000 + t1.microsecond
t2_ms = (t2.hour*60*60 + t2.minute*60 + t2.second)*1000 + t2.microsecond

delta_ms = max([t1_ms, t2_ms]) - min([t1_ms, t2_ms])

It's a little lame, but it works.
