Introduction
------------
This module allows complex timezone operations in domains mimicing python's
pytz. The heavy lifting is done by http://momentjs.com/timezone.
It is meant to allow correct filters for 'Today', 'Yesterday' etc.
In addition to implementing a subset of `pytz.tzinfo` and
`datetime.astimezone`, there's a shortcut called `utc_today()` which returns
the beginning of the day in the current user's time zone translated to UTC,
this is equivalent to::
pytz.timezone(tz).localize(datetime.datetime.now().replace(hour=0, minute=0,
second=0)).astimezone(pytz.utc)
in python.
Usage
-----
Depend on this module and use filters like::
[('write_date', '>=', utc_today().strftime('%Y-%m-%d'))]
which displays records changed in the user's conception of today.""",
