Is there a way of "adding" 4 hours and getting a jump of 5 hours on March 8th, 2015 (due to Daylight Savings Time), without hardcoding when to spring forward and when to fall back? I'd love it if there's some library that'll do this for me.#!/usr/bin/python import pytz import datetime def main(): # On 2015-03-08, 2:00 AM to 2:59AM Pacific time does not exist - the clock jumps forward an hour. weird_naive_datetime = datetime.datetime(2015, 3, 8, 1, 0, 0).replace(tzinfo=pytz.timezone('US/Pacific')) weird_tz_aware_datetime = weird_naive_datetime.replace(tzinfo=pytz.timezone('US/Pacific')) print(weird_tz_aware_datetime) four_hours=datetime.timedelta(hours=4) print('Four hours later is:') print(weird_tz_aware_datetime + four_hours) print('...but I want numerically 5 hours later, because of Daylight Savings Time') main() Thanks!
The pyzt module (which you've imported) has lots to say about this. Look at its procedures "localize' and 'normalize' and all the rest of the pyzt documentation.
