Is "US/Eastern" the same thing as "America/New_York"? According to my system, they are symlinks to the same content. So they are actually the same time zone. It's a time zone that has different UTC offsets at different points in time, both historic (the change from local to standard time) and modern (a twice-yearly shift in clocks), but it's the same timezone. If you look at any other form that means "New_York" (eg "EST"), and then set the date way back, you should see the same phenomenon. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
