There are some technical differences between UTC and GMT, which almost
never come up, and which I very much doubt are significant here (does
pytz care about leap seconds?). But what I'm seeing - at least in the
version of pytz that I picked up by typing 'sudo pip install pytz' on
Debian Wheezy - is that the two are different types. UTC seems to be a
special case, while GMT is like the others. That may be why they're
not comparing equal, even though all operations might happen to
produce the same results.
