Ok, first of all I want to say I'm no Python programmer/developer.
However, I recently posted a 'bug' for a Linux/Windows program I'm using
very much which is based in Python. The program is called Anki and it's
designed to help you remember facts (such as words and phrases in a
foreign language) as easily, quickly and efficiently as possible.

Here, http://code.google.com/p/anki/issues/detail?id=613, you'll find my
explanation of the 'bug'.

Briefly, I live in Argentina and the current administration has changed
current time because of 'daylight saving'. However, when syncing my
decks (which store all my cards) with Anki's server, it tells me my
current time is wrong and that I need to change it. In fact, it's not MY
clock which is wrong, but Anki's. So, I posted this bug and the
developer, as you can see, told me that: it's not really anki's job - a
setting to shift the clock would need changes all throughout the code.
probably something in python's timezone handling needs to be updated.
could you post about the daylight savings issue on the python mailing
list and see what they say? So, this is what I'm doing. 

Right now I will notify the developer of this program that, actually,
Python already handles 'time saving'.

Thanks for your help. Any other comments/ideas would be greatly appreciated.
