pytz

Im working on converting epoch timestamps to dates in different timezones with pytz. What I am trying to do is create a DateTime object that accepts an Olson database timezone and an epoch time and returns a localized datetime object. Eventually I need to answer questions like "What hour was it in New York at epoch time 1350663248?" Something is not working correctly here: import datetime, pytz, time class DateTime: def __init__(self, timezone, epoch): self.timezone = timezone self.epoch = epoch timezoneobject = pytz.timezone(timezone) datetimeobject = datetime.datetime.fromtimestamp( self

Is there a simple way to remove the timezone from a pytz datetime object? e.g. reconstructing dt from dt_tz in this example: >>> import datetime >>> import pytz >>> dt = datetime.datetime.now() >>> dt datetime.datetime(2012, 6, 8, 9, 27, 32, 601000) >>> dt_tz = pytz.utc.localize(dt) >>> dt_tz datetime.datetime(2012, 6, 8, 9, 27, 32, 601000, tzinfo=<UTC>) user1094786 To remove a timezone (tzinfo) from a datetime object: # dt_tz is a datetime.datetime object dt = dt_tz.replace(tzinfo=None) If you are using a library like arrow , then you can remove timezone by simply converting an arrow object

Using pytz and Python 3.4, how to get the first datetime of a given day (lets say, 2014-10-19), in a given timezone (lets say 'America/Sao_Paulo' )? Use localize() method to attach the timezone: from datetime import datetime import pytz # $ pip install pytz tz = pytz.timezone('America/Sao_Paulo') naive = datetime(2014, 10, 19) aware = tz.localize(naive, is_dst=None) If you run the code; it generates NonExistentTimeError . How to deal with this error depends on the application e.g., to get some valid local time near the midnight: aware = tz.normalize(tz.localize(naive, is_dst=False)) Or you

Is there a cross-platform function in python (or pytz ) that returns a tzinfo object corresponding to the timezone currently set on the computer? environment variables cannot be counted on as they are not cross-platform >>> import datetime >>> today = datetime.datetime.now() >>> insummer = datetime.datetime(2009,8,15,10,0,0) >>> from pytz import reference >>> localtime = reference.LocalTimezone() >>> localtime.tzname(today) 'PST' >>> localtime.tzname(insummer) 'PDT' >>> tzlocal module that returns pytz timezones works on *nix and win32: from datetime import datetime from tzlocal import get

I keep getting the following error while running Python code: C:\Python26\lib\site-packages\pytz\__init__.py:32: UserWarning: Module pytz was already imported from C:\Python26\lib\site-packages\pytz\__init__.pyc, but c:\python26\lib\site-packages\pytz-2011h-py2.6.egg is being added to sys.path from pkg_resources import resource_stream What does it mean and how can I solve it? You've got the package installed in pytz and also as a .egg . Remove the .egg and you won't get the warning. However, note that it's referred to as a "spurious warning" -- this isn't actually a problem, though it could

I'm reading the not so complete pytz documentation and I'm stuck on understand one part of it. Converting between timezones also needs special attention. This also needs to use the normalize method to ensure the conversion is correct. >>> utc_dt = utc.localize(datetime.utcfromtimestamp(1143408899)) >>> utc_dt.strftime(fmt) '2006-03-26 21:34:59 UTC+0000' >>> au_tz = timezone('Australia/Sydney') >>> au_dt = au_tz.normalize(utc_dt.astimezone(au_tz)) >>> au_dt.strftime(fmt) '2006-03-27 08:34:59 EST+1100' >>> utc_dt2 = utc.normalize(au_dt.astimezone(utc)) >>> utc_dt2.strftime(fmt) '2006-03-26 21:34
