推荐答案

这是 ISO 8601 兼容字符串.有许多可以转换的库.但是，要将其与时区转换结合使用，您可以:

This is an ISO 8601 compliant string. There are various libraries that can convert this. But to combine this with a Timezone conversion, you can:

import datetime as dt
from pytz import timezone

def convert_my_iso_8601(iso_8601, tz_info):
    assert iso_8601[-1] == 'Z'
    iso_8601 = iso_8601[:-1] + '000'
    iso_8601_dt = dt.datetime.strptime(iso_8601, '%Y-%m-%dT%H:%M:%S.%f')
    return iso_8601_dt.replace(tzinfo=timezone('UTC')).astimezone(tz_info)

my_dt = convert_my_iso_8601('2017-01-17T20:02:45.767Z', timezone('MST'))
