Question

我在欧盟时区有一个日期时间列表：

[u'2014-11-01T09:00:00+01:00', u'2014-11-02T00:00:00+01:00', u'2014-11-03T00:00:00+01:00', u'2014-11-04T00:00:00+01:00', u'2014-11-05T00:00:00+01:00', u'2014-11-06T00:00:00+01:00', u'2014-11-07T00:00:00+01:00', u'2014-11-08T00:00:00+01:00', u'2014-11-09T00:00:00+01:00', u'2014-11-10T00:00:00+01:00', u'2014-11-11T00:00:00+01:00', u'2014-11-12T00:00:00+01:00', u'2014-11-13T00:00:00+01:00', u'2014-11-14T00:00:00+01:00', u'2014-11-15T00:00:00+01:00', u'2014-11-16T00:00:00+01:00', u'2014-11-17T00:00:00+01:00', u'2014-11-18T00:00:00+01:00', u'2014-11-19T00:00:00+01:00', u'2014-11-20T00:00:00+01:00', u'2014-11-21T00:00:00+01:00', u'2014-11-22T00:00:00+01:00', u'2014-11-23T00:00:00+01:00', u'2014-11-24T00:00:00+01:00', u'2014-11-25T00:00:00+01:00', u'2014-11-26T00:00:00+01:00', u'2014-11-27T00:00:00+01:00', u'2014-11-28T00:00:00+01:00', u'2014-11-29T00:00:00+01:00', u'2014-11-30T00:00:00+01:00', u'2014-12-01T00:00:00+01:00']

如何将每个转换为PST时区？

Answer 1

这应该这样做：

from pytz import timezone
import pytz
from dateutil.parser import parse

l = [u'2014-11-01T09:00:00+01:00', u'2014-11-02T00:00:00+01:00', u'2014-11-03T00:00:00+01:00', u'2014-11-04T00:00:00+01:00', u'2014-11-05T00:00:00+01:00', u'2014-11-06T00:00:00+01:00', u'2014-11-07T00:00:00+01:00', u'2014-11-08T00:00:00+01:00', u'2014-11-09T00:00:00+01:00', u'2014-11-10T00:00:00+01:00', u'2014-11-11T00:00:00+01:00', u'2014-11-12T00:00:00+01:00', u'2014-11-13T00:00:00+01:00', u'2014-11-14T00:00:00+01:00', u'2014-11-15T00:00:00+01:00', u'2014-11-16T00:00:00+01:00', u'2014-11-17T00:00:00+01:00', u'2014-11-18T00:00:00+01:00', u'2014-11-19T00:00:00+01:00', u'2014-11-20T00:00:00+01:00', u'2014-11-21T00:00:00+01:00', u'2014-11-22T00:00:00+01:00', u'2014-11-23T00:00:00+01:00', u'2014-11-24T00:00:00+01:00', u'2014-11-25T00:00:00+01:00', u'2014-11-26T00:00:00+01:00', u'2014-11-27T00:00:00+01:00', u'2014-11-28T00:00:00+01:00', u'2014-11-29T00:00:00+01:00', u'2014-11-30T00:00:00+01:00', u'2014-12-01T00:00:00+01:00']
amsterdam = timezone('Europe/Amsterdam')
pst = timezone('US/Pacific')
[parse(d).replace(tzinfo=amsterdam).astimezone(pst) for d in l]

Answer 2

有两个独立的任务：

将rfc 3339日期/时间格式解析为知晓日期时间对象

>>> from dateutil.parser import parse
>>> aware_dt = parse('2014-11-01T09:00:00+01:00')
>>> aware_dt
datetime.datetime(2014, 11, 1, 9, 0, tzinfo=tzoffset(None, 3600))

将其转换为America/Los_Angeles时区

>>> import pytz
>>> tz = pytz.timezone('America/Los_Angeles')
>>> tz.normalize(aware_dt.astimezone(tz))
datetime.datetime(2014, 11, 1, 1, 0, tzinfo=<DstTzInfo 'America/Los_Angeles' PDT-1 day, 17:00:00 DST>)

将日期时间从欧盟时区转换为PST
