getting difference of 2 time since epoch in days

Question

I was wondering for a short way to do this:

Lets say I have 2 time since epoch: 1418647594 and 1418177737 ; how would I get the difference of the 2 ? 之差？ I know there are similar questions but they involve installing modules. This one is slightly different!

Thanks for the help.

Answer 1

tStart = 1418177737
tStop = 1418647594
tElapsed = tStop - tStart
diffSeconds = tElapsed / 1000 % 60
diffMinutes = tElapsed / (60 * 1000) % 60
diffHours = tElapsed / (60 * 60 * 1000) % 24
diffDays = tElapsed / (24 * 60 * 60 * 100)

Answer 2

you can use datetime:

>>> import datetime
>>> diff = datetime.datetime.fromtimestamp(1418647594) - datetime.datetime.fromtimestamp(1418177737)
>>> diff
datetime.timedelta(5, 37857)
>>> diff.days
5
