Merge lp:~ahasenack/ubuntu/precise/python-tz/day-leap-fix-885163 into lp:ubuntu/precise/python-tz

[Andreas Hasenack]

This branch has the patch from bug #885163, done by Forest Bond. I tested it in oneiric and lucid and I intend to do an SRU release for those plus natty and maverick. The first step is to get this into precise.

My testcase was Landscape, which had a few broken pages due to this bug. With the patched package installed, Landscape worked again (tested on lucid and oneiric).

[Andreas Hasenack (ahasenack)]

This other test case, taken from a bug comment, can also be used:

#!/usr/bin/python
import pytz
from datetime import datetime
tz = pytz.timezone("Pacific/Apia")
d2 = datetime(2012,1,1)
local = tz.localize(d2)
local.dst()
print "All is good, NOT hit by bug #885163!"
