utcnow

[Joost Molenaar]

Time zones! So much fun. Looks like you're dealing with UTC offsets
yourself, which gets messy as soon as you start thinking about DST. The
good news is that there's a timezone database on most systems, which you
should almost definitely use.

Take a look at python-dateutil (pip install python-dateutil):

>>> from datetime import datetime
>>> from dateutil import tz
>>> datetime.now()
datetime.datetime(2012, 9, 17, 6, 33, 57, 158555)

This is a so-called "naive datetime", it doesn't know about timezones. On
my system, it returns a time in my local time zone. (It could have been GMT
or something else entirely.) You have to call .replace() on a "naive
datetime" to set the tzinfo member to make it a timezone-aware datetime
object:

>>> AMS = tz.gettz('Europe/Amsterdam')
>>> ATH = tz.gettz('Europe/Athens')
>>> datetime.now().replace(tzinfo=AMS).astimezone(ATH)
datetime.datetime(2012, 9, 17, 7, 37, 38, 573223,
tzinfo=tzfile('/usr/share/zoneinfo/Europe/Athens'))

Voila, it seems like you're one hour ahead of me. :-)

HTH,

Joost
