Generate RFC 3339 timestamp in Python

I'm trying to generate an RFC 3339 UTC timestamp in Python. So far I've been able to do the following:

>>> d = datetime.datetime.now()
>>> print d.isoformat('T')

My problem is with setting the UTC offset.

According to the docs, the classmethod
, takes an optional
argument where
tz must be an instance of a class tzinfo subclass
, and
an abstract base class for time zone information objects.

This is where I get lost- How come tzinfo is an abstract class, and how am I supposed to implement it?

(NOTE: In PHP it's as simple as
timestamp = date(DATE_RFC3339);
, which is why I can't understand why Python's approach is so convoluted...)

Further down in the same doc that you linked to, it explains how to implement it, giving some examples, including full code for a UTC class (representing UTC), a FixedOffset class (representing a timezone with a fixed offset from UTC, as opposed to a timezone with DST and whatnot), and a few others.
