Convert possibly incorrect time to seconds

Question

Having such string 12:65:84 and told that it represents time in h:m:s AND values there can be not correct, e.g. 65 minutes that should be translated to 1 hour and 5 minutes

I need to reduce these numbers to total amount of seconds.

Naive solution will be:

time_string = '12:65:84'
hours, minutes, seconds = [int(i) for i in time_string.split(':')
total_seconds = hours * 60 * 60 + minutes * 60 + seconds

Question: How it can be done better, ideally without using any import, maybe with some combination of map, reduce and their friends?

Any datetime module you get will parse the time string and throws error for incorrect values. Your algorithm works, what's the problem? — Trimax, Aug 04 '16 at 08:48
@Trimax, no problems here, just question: "how to do better?". Maybe with `reduce` or something — micgeronimo, Aug 04 '16 at 08:50

*"12:65:84"* time in `h:m:s` - what am I missing here? 65 minutes? Please @micgeronimo explain? — Bogdan Bogdanov, Aug 04 '16 at 09:09
@BogdanBogdanov, yes values there can be invalid, if it was valid I'd just used `strptime` — micgeronimo, Aug 04 '16 at 09:14

You can also use timedelta for the same as:

s='12:65:84'
h,m,s=[int(i) for i in s.split(':')]
t=timedelta(hours=h, seconds=s, minutes=m)
res=t.total_seconds()
