I get similar results, except with hours 01:00:00 and 02:00:00.  I am in
US Central time (GMT-6).

>>> int(time.mktime(time.strptime('2007-03-11 00:00:00','%Y-%m-%d
%H:%M:%S')))
1173592800
>>> int(time.mktime(time.strptime('2007-03-11 01:00:00','%Y-%m-%d
%H:%M:%S')))
1173596400
>>> int(time.mktime(time.strptime('2007-03-11 02:00:00','%Y-%m-%d
%H:%M:%S')))
1173596400
>>> int(time.mktime(time.strptime('2007-03-11 03:00:00','%Y-%m-%d
%H:%M:%S')))
1173600000
