I would like to know what are all the possible values for the timezone argument in the Python library pytz. How to do it?

The pytz package encourages using UTC for internal timezone representation by including a special UTC implementation based on the standard Python reference implementation in the Python documentation. The UTC timezone unpickles to be the same instance, and pickles to a smaller size than other pytz tzinfo instances.
Timedelta and DSTpytz will help you to tell if an date is under DST influence by checking dst() method.
pytz brings the Olson tz database into Python. This library allows accurate and cross platform timezone calculations using Python 2.4 or higher. It also solves the issue of ambiguous times at the end of daylight saving time, which you can read more about in the Python Library Reference ( datetime. tzinfo ).
pytz is a Python module mostly used for resolving the issues related to time zone differences. This module determines the time of any region using the local timezone name taking UTC time as the reference. The datetime is a python built-in library.
You can list all the available timezones with pytz.all_timezones:
In [40]: import pytz In [41]: pytz.all_timezones Out[42]: ['Africa/Abidjan', 'Africa/Accra', 'Africa/Addis_Ababa', ...] There is also pytz.common_timezones:
In [45]: len(pytz.common_timezones) Out[45]: 403 In [46]: len(pytz.all_timezones) Out[46]: 563 Don't create your own list - pytz has a built-in set:
import pytz set(pytz.all_timezones_set) >>> {'Europe/Vienna', 'America/New_York', 'America/Argentina/Salta',..} You can then apply a timezone:
import datetime tz = pytz.timezone('Pacific/Johnston') ct = datetime.datetime.now(tz=tz) >>> ct.isoformat() 2017-01-13T11:29:22.601991-05:00 Or if you already have a datetime object that is TZ aware (not naive):
# This timestamp is in UTC my_ct = datetime.datetime.now(tz=pytz.UTC) # Now convert it to another timezone new_ct = my_ct.astimezone(tz) >>> new_ct.isoformat() 2017-01-13T11:29:22.601991-05:00 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
