How can I remove a pytz timezone from a datetime object?

问题 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>) 回答1: 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

delorean docs show this way to get the current time in a given timezone using datetime : from datetime import datetime from pytz import timezone EST = "US/Eastern" UTC = "UTC" d = datetime.utcnow() utc = timezone(UTC) est = timezone(EST) d = utc.localize(d) d = est.normalize(EST) and compare it with the delorian-based code: from delorean import Delorean EST = "US/Eastern" d = Delorean(timezone=EST) I believe the datetime example should be written as: from datetime import datetime import pytz eastern_timezone = pytz.timezone("US/Eastern") d = datetime.now(eastern_timezone) that is more concise.

This question already has an answer here: Is a specific timezone using DST right now? 1 answer We have a server that runs on GMT time. I need to write a Python script that determines if it's currently (at this very second) Daylight Savings Time (DST) in Los Angeles, CA. How can I accomplish this? I took a look at pytz and time, but I can't figure it out. I realize that I could create some logic such as comparing the current time in LA to GMT time, but it would be a lot cleaner if I could use a standard library instead. Thanks Edit: Here's some sample code of me setting up the timezone: from

问题 I'm trying to compare two times using the Python datetime module, but I can't seem to create a timezone-aware time object in UTC. >>> import pytz, datetime >>> UTC_TZ = pytz.utc >>> EASTERN_TZ = pytz.timezone('America/New_York') >>> d1 = datetime.time(10, tzinfo = UTC_TZ) >>> d1 datetime.time(10, 0, tzinfo=<UTC>) >>> d2 = datetime.time(10, tzinfo = EASTERN_TZ) >>> d2 datetime.time(10, 0, tzinfo=<DstTzInfo 'America/New_York' EST-1 day, 19:00:00 STD>) >>> d1 < d2 Traceback (most recent call

unexpected results converting timezones in python

I'm trying to understand why I'm getting these results when converting timezones to UTC: In [74]: d1 = datetime(2007, 12, 5, 6, 30,tzinfo=pytz.timezone('US/Pacific')) In [75]: d1 Out[75]: datetime.datetime(2007, 12, 5, 6, 30, tzinfo=<DstTzInfo 'US/Pacific' LMT-1 day, **16:07:00 STD**>) In [76]: d1.astimezone(pytz.utc) Out[76]: datetime.datetime(2007, 12, 5, 14, 23, tzinfo=<UTC>) Why did 6:30am become 2:23pm? On the other hand, if I use the following approach, I get the expected result: In [90]: d2 = datetime(2007, 12, 5, 6, 30) In [91]: uspac = pytz.timezone('US/Pacific') In [92]: d2_aware =

问题 I'm having trouble understanding the conversion between the "Etc/GMT-5" timezone and UTC in pytz. >>> dt = datetime(2009, 9, 9, 10, 0) # September 9 2009, 10:00 >>> gmt_5 = pytz.timezone("Etc/GMT-5") >>> gmt_5.localize(dt) datetime.datetime(2009, 9, 9, 10, 0, tzinfo=<StaticTzInfo 'Etc/GMT-5'>) Everything is fine so far, but then I try to convert that to UTC: >>> gmt_5.localize(dt).astimezone(pytz.utc) datetime.datetime(2009, 9, 9, 5, 0, tzinfo=<UTC>) So to me it seems that when converting

Why doesn't pytz localize() produce a datetime object with tzinfo matching the tz object that localized it?

pytz.astimezone not accounting for daylight savings?

问题 On 2013 Jun 1 I expect the "PST8PDT" timezone to behave like GMT+7, as it is daylight savings in that timezone. However, it behaves like GMT+8: >>> import pytz, datetime >>> Pacific = pytz.timezone("PST8PDT") >>> datetime.datetime(2013, 6, 1, 12, tzinfo=Pacific).astimezone(pytz.utc) datetime.datetime(2013, 6, 1, 20, 0, tzinfo=<UTC>) In contrast, on 2013 Jan 1 it behaves (correctly) like GMT+8: >>> datetime.datetime(2013, 1, 1, 12, tzinfo=Pacific).astimezone(pytz.utc) datetime.datetime(2013, 1

Then it uses the astimezone function to adjust the time according to
