title: How do I use timezones with a datetime object in python?
body: <p>How do I properly represent a different timezone in my timezone? The below example only works because I know that EDT is one hour ahead of me, so I can uncomment the subtraction of myTimeZone()</p>
  
  <pre><code>import datetime, re
  from datetime import tzinfo
  
  class myTimeZone(tzinfo):
      """docstring for myTimeZone"""
      def utfoffset(self, dt):
          return timedelta(hours=1)
  
  def myDateHandler(aDateString):
      """u'Sat,  6 Sep 2008 21:16:33 EDT'"""
      _my_date_pattern = re.compile(r'\w+\,\s+(\d+)\s+(\w+)\s+(\d+)\s+(\d+)\:(\d+)\:(\d+)')
      day, month, year, hour, minute, second = _my_date_pattern.search(aDateString).groups()
      month = [
              'JAN', 'FEB', 'MAR', 
              'APR', 'MAY', 'JUN', 
              'JUL', 'AUG', 'SEP', 
              'OCT', 'NOV', 'DEC'
      ].index(month.upper()) + 1
      dt = datetime.datetime(
          int(year), int(month), int(day), 
          int(hour), int(minute), int(second)
      )                   
      # dt = dt - datetime.timedelta(hours=1)
      # dt = dt - dt.tzinfo.utfoffset(myTimeZone())
      return (dt.year, dt.month, dt.day, dt.hour, dt.minute, dt.second, 0, 0, 0)
  
  def main():
      print myDateHandler("Sat,  6 Sep 2008 21:16:33 EDT")
  
  if __name__ == '__main__':
      main()
