22598	make_aware throws AmbiguousTimeError exception	trott@…	nobody	"When using the pytz package, the ''make_aware()'' utility function occasionally throws an AmbiguousTimeError or NonExistentTimeError exception.
As the pytz maintainer explain, some dates time values may not be localizable (using the pytz.localize() function) when the optional is_dst Parameter is
None.

I don't think, that Django should throw an exception in these cases, that results in a ""show stopper"" behavior. 
Instead, I would prefer to just ""guess"" it the is_dst parameter when these Exceptions occur. That may result in a 50% chance to get a 1 hour
miscalculation – but until we don't know a better way, I just prefer that instead of having some values not saved at all...

Anyway, I attached a little patch to prevent this nasty Exceptions."	New feature	closed	Utilities	dev	Normal	fixed	make_aware		Ready for checkin	1	0	0	0	0	0
