Unfortunately, mx.DateTime also ignores the time zone.  If 
I parse the PST time, and ask for the result's time zone it 
gives me my local time zone.

I have had some luck with dateutil:

>>> import dateutil.parse as p 
>>> p.parse("10:29:52 Feb 29, 2008 PST")
datetime.datetime(2008, 2, 29, 10, 29, 52)

and if I hand it a list of time zones, it does the right thing

>>> zones = {"PST": -8*60*60}
p.parse("10:29:52 Feb 29, 2008 PST", tzinfos=zones)
datetime.datetime(2008, 2, 29, 10, 29, 52, tzinfo=tzoffset('PST', -28800))

But I cannot figure out how to get dateutil to use the 
zoneinfo file that it includes in its own package.  It has a
zoneinfo-2007k.tar.gz right in the package, and a class 
to parse the binary zoneinfo, but no clear way to get it to
parse its own file and use those during the parsing.
