variables for moscow, pacific, and india
using datetime.timezone?
Link to 3 part challenge: http://teamtreehouse.com/library/dates-and-times-in-python/where-on-earth-do-timezones-make-sense/timezone-maker
This was really confusing... It seemed obvious, I tried
moscow = datetime.timezone + 4
...but it said something about type and int not being compatible! AAAARRRGGG!
Why aren't they compatible?
I almost broke down and started using pytz,
but I saw there were a bunch of forum posts that used timedelta for time zones,
so in the end I came up with (after much trial and error):
import datetime
moscow = datetime.timezone(datetime.timedelta(hours=4))
pacific = datetime.timezone(datetime.timedelta(hours=-8))
india = datetime.timezone(datetime.timedelta(hours=+5.5))
..and for some reason (??) it passed.
Note: I also spent an hour fiddling around with astimezone() to no avail.
Hopefully others doing this Python DateTime find this post and aren't as frustrated as I was..

With one exception: india's time zone should be written as (hours=+5, minutes=+30) instead of (hours=+5.5), as this is more correct and will always work without exception.
