在Python中将时区偏移量应用于日期时间 [英] Apply timezone offset to datetime in Python
本文介绍了在Python中将时区偏移量应用于日期时间的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
对于给定的日期字符串(例如2009-01-01T12:00:00+0100
),我想要UTC日期时间对象.
For a given date string such as 2009-01-01T12:00:00+0100
I want the UTC datetime object.
from datetime import datetime
datetime.strptime("2013-03-21T14:19:42+0100", "%Y-%m-%dT%H:%M:%S%z")
返回
datetime.datetime(2013, 3, 21, 14, 19, 42, tzinfo=datetime.timezone(datetime.timedelta(0, 3600)))
我不敢相信datetime
或pandas
中没有方法将与时区相关的偏移量应用于日期时间并返回纯UTC日期时间.
I cannot believe there is no method in datetime
or pandas
for applying the timezone-related offset to the datetime and returning plain UTC datetime.
如何应用tzinfo
偏移量/增量,以使所得时区为普通UTC(tzinfo=None
)?
How can I apply the tzinfo
offset/delta, so that the resulting timezone is plain UTC (tzinfo=None
)?
推荐答案
这感觉有点脏,但确实有效
This feels a bit dirty but it does work
from datetime import datetime
orig_dt = datetime.strptime("2013-03-21T14:19:42+0100", "%Y-%m-%dT%H:%M:%S%z") # datetime.datetime(2013, 3, 21, 14, 19, 42, tzinfo=datetime.timezone(datetime.timedelta(0, 3600)))
utc_time_value = orig_dt - orig_dt.utcoffset()
utc_dt = utc_time_value.replace(tzinfo=None) # datetime.datetime(2013, 3, 21, 13, 19, 42)
