How to create timezone aware datetime objects in python given UTC offset in seconds.

gistfile1.py

import datetime

class AnyTimeZone(datetime.tzinfo):
	# Define this somewhere, and import it whenever you need to make TZ aware datetime objects

	def __init__(self, utc_offset, is_dst):
		self.utc_offset = utc_offset
		self.dst_on = is_dst

	def utcoffset(self, dt):
		return datetime.timedelta(seconds=self.utc_offset) + self.dst(dt)

	def dst(self, dt):
		if self.dst_on:
			return datetime.timedelta(hours=1)
		else:
			return datetime.timedelta(hours=0)

	def tzname(self, dt):
		 return "My_TZ_Name"
		 
# Using the class:

easter_std_time = AnyTimeZone(utc_offset=3600*4, is_dst=False) # Create the EST timezone object

tz_aware_dt_now = datetime.datetime.now(easter_std_time) # A timezone aware datetime object of current time
tz_aware_dt = datetime.datetime.fromtimestamp(1324454875, easter_std_time)
