I'd say if the documentation mentions it, but doesn't say why, then we're not gonna be able to do much better for you as far as "why" goes.
http://pytz.sourceforge.net/ "Unfortunately using the tzinfo argument of the standard datetime constructors "does not work" with pytz for many timezones." But it looks like they suggest something along the lines of... timezone('Europe/Amsterdam').localize(datetime(2018, 12, 17, 11, 31, 26)) >From the examples on http://pytz.sourceforge.net/#problems-with-localtime ... >>> eastern = timezone('US/Eastern') >>> fmt = '%Y-%m-%d %H:%M:%S %Z%z' >>> loc_dt = datetime(2002, 10, 27, 1, 30, 00) >>> est_dt = eastern.localize(loc_dt, is_dst=True) >>> edt_dt = eastern.localize(loc_dt, is_dst=False) >>> print(est_dt.strftime(fmt) + ' / ' + edt_dt.strftime(fmt)) 2002-10-27 01:30:00 EDT-0400 / 2002-10-27 01:30:00 EST-0500 Browse through their examples and see if you can find something similar that works for you. -----Original Message----- From: Python-list [mailto:python-list-bounces+david.raymond=tomtom....@python.org] On Behalf Of Jaap van Wingerde Sent: Wednesday, February 06, 2019 9:27 AM To: python-list@python.org Subject: timezones I made a small script to practise with timezones: #!/usr/bin/env python3 # -*- coding: utf_8 -*- from datetime import datetime, timedelta from pytz import timezone import pytz amsterdam_datetime = datetime(2018, 12, 17, 11, 31, 26, tzinfo=timezone('Europe/Amsterdam')) print(amsterdam_datetime) utc_datetime = amsterdam_datetime.astimezone(pytz.utc) print(utc_datetime) amsterdam_datetime = datetime(2018, 6, 17, 11, 31, 26, tzinfo=timezone('Europe/Amsterdam')) print(amsterdam_datetime) utc_datetime = amsterdam_datetime.astimezone(pytz.utc) print(utc_datetime) The output of the script is: 2018-12-17 11:31:26+00:20 2018-12-17 11:11:26+00:00 2018-06-17 11:31:26+00:20 2018-06-17 11:11:26+00:00 I respected: 2018-12-17 11:31:26+01:00 2018-12-17 10:31:26+00:00 2018-06-17 11:31:26+02:00 2018-06-17 09:31:26+00:00 I need this functionality for adjusting wrong timestamps in Android JPG-images as the 'Exif.GPSInfo.GPSTimeStamp' and 'Exif.GPSInfo.GPSDateStamp' are missing. Why I get this unrespected results?
