原标题:Parsing time string in Python

我有一天的时间表明,我不知道如何把它 par在沙里。

举动就是这样:

Tue May 08 15:14:45 +0800 2012

审判

datetime.strptime("Tue May 08 15:14:45 +0800 2012","%a %b %d %H:%M:%S %z %Y")

但是,有人说

 z  is a bad directive in format  %a %b %d %H:%M:%S %z %Y 

据Sharma说:

%z UTC被+HHMM或HMM(如果目标为na)所抵消。

www.un.org/spanish/ecosoc 说明这一时间的适当格式是什么?

http://docs.python.org/library/time.html#time.strptime"rel=“noreferer”>strptime(

大致如下:

>>> from datetime import datetime
>>> date_str =  Tue May 08 15:14:45 +0800 2012 
>>> date = datetime.strptime(date_str,  %a %B %d %H:%M:%S +0800 %Y )
>>> date
datetime.datetime(2012, 5, 8, 15, 14, 45)

令人不快的是,也许其他人可以帮助他这样做。

http://docs.python.org/library/time.html#time.strftime”rel=“noreferer”>http://docs.python.org/library/time.html#time.strftime 。 印刷版也一样。

帮助的希望

PS, Your best bet for timezones in installing pytz from pypi. ( http://pytz.sourceforge.net/ ) in fact I think pytz has a great datetime parsing method if i remember correctly. The standard lib is a little thin on the ground with timezone functionality.

这里的“平衡解决办法”支持投入时间中可变的定额:

>>> from email.utils import parsedate_tz, mktime_tz
>>> from datetime import datetime, timedelta
>>> timestamp = mktime_tz(parsedate_tz( Tue May 08 15:14:45 +0800 2012 ))
>>> utc_time = datetime(1970, 1, 1) + timedelta(seconds=timestamp)
>>> utc_time
datetime.datetime(2012, 5, 8, 7, 14, 45)

It has discussed many times in SO. In short, "%z" is not supported because platform not support it. My solution is a new one, just skip the time zone.:

    datetime.datetime.strptime(re.sub(r"[+-]([0-9])+", "", "Tue May 08 15:14:45 +0800 2012"),"%a %b %d %H:%M:%S %Y")
