when does `datetime.now(pytz_timezone)` fail?

问题 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

Use Python to find out if a timezone currently in daylight savings time [duplicate]

问题 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

unexpected results converting timezones in python

由 Deadly 提交于 2019-11-26 12:43:16
问题 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:

How to get system timezone setting and pass it to pytz.timezone?

由 一个人想着一个人 提交于 2019-11-26 11:22:29
We can use time.tzname get a local timezone name, but that name is not compatible with pytz.timezone . In fact, the name returned by time.tzname is ambiguous. This method returns ('CST', 'CST') in my system, but 'CST' can indicate four timezones: Central Time Zone (North America) - observed in North America's Central Time Zone China Standard Time Chungyuan Standard Time - the term "Chungyuan Standard Time" is now rarely in use in Taiwan Australian Central Standard Time (ACST) tzlocal module returns pytz tzinfo's object corresponding to the local timezone: import time from datetime import

pytz localize vs datetime replace

问题 I\'m having some weird issues with pytz\'s .localize() function. Sometimes it wouldn\'t make adjustments to the localized datetime: .localize behaviour: >>> tz <DstTzInfo \'Africa/Abidjan\' LMT-1 day, 23:44:00 STD> >>> d datetime.datetime(2009, 9, 2, 14, 45, 42, 91421) >>> tz.localize(d) datetime.datetime(2009, 9, 2, 14, 45, 42, 91421, tzinfo=<DstTzInfo \'Africa/Abidjan\' GMT0:00:00 STD>) >>> tz.normalize(tz.localize(d)) datetime.datetime(2009, 9, 2, 14, 45, 42, 91421, tzinfo=<DstTzInfo \

Datetime Timezone conversion using pytz

由 不羁岁月 提交于 2019-11-26 04:26:40
问题 This is just another post on pytz . There are two functions to convert datetime objects between two timezones. The second functions works for all cases. The first function fails in two cases, (3) and (4). Similar SO post did not have an issue like this. Any explanation based on the difference between localize(datetime.datetime) and replace(tzinfo) would be a great help. >>> from dateutil.parser import parse >>> import pytz First function (buggy) The function below uses datetime.datetime

Python datetime object show wrong timezone offset

由 一曲冷凌霜 提交于 2019-11-26 03:58:56
问题 I am try creating a datetime object in python using datetime and pytz, the offset shown is wrong. import datetime from pytz import timezone start = datetime.datetime(2011, 6, 20, 0, 0, 0, 0, timezone(\'Asia/Kolkata\')) print start The output shown is datetime.datetime(2011, 6, 20, 0, 0, tzinfo=<DstTzInfo \'Asia/Kolkata\' HMT+5:53:00 STD>) Note that \'Asia/Kolkata\' is IST which is GMT+5:30 and not HMT+5:53. This is a standard linux timezone, why do I get this wrong, and how do I solve it? 回答1

This is a little strange, does anyone experience the same issue? In fact I\'m getting different behavior between import pytz from datetime import datetime hk = pytz.timezone(\'Asia/Hong_Kong\') dt1 = datetime(2012,1,1,tzinfo=hk) dt2 = hk.localize(datetime(2012,1,1)) if dt1 > dt2: print \"Why?\" 回答1: Time zones and offsets change over the years.
