I am working with an API that is returning a JSON string that contains the following date/time in it:
2013-03-14T14:15:23-07:00
I get the date and the time, down to the second. But the last 5 characters are confusing me. I'm guessing that's a UTC offset. (mountain time) What i can't figure out how to do is to compare the above string to a date/time in python. The T is also throwing me off.
How do I encode a python date/time string to match the above?
如果您使用该python-dateutil库（https://crate.io/packages/python-dateutil/），您可以将该值转换为datetime.
>>> dateutil.parser.parse('2013-03-14T14:15:23-07:00')
datetime.datetime(2013, 3, 14, 14, 15, 23, tzinfo=tzoffset(None, -25200))
您正在查看ISO 8601日期格式。您可以使用包来解析它或自己做。
您可以使用 datetime.strptime 来解析：
>>> ts='2013-03-14T14:15:23-07:00'
>>> datetime.datetime.strptime(ts[0:-6],'%Y-%m-%dT%H:%M:%S')
datetime.datetime(2013, 3, 14, 14, 15, 23)
然后只需添加/减去时间增量（对于“天真”对象）：
>>> datetime.timedelta(hours=int(ts[-6:-3]))
datetime.timedelta(-1, 61200)
所以：
>>> d=datetime.datetime.strptime(ts[0:-6],'%Y-%m-%dT%H:%M:%S')+datetime.timedelta(hours=int(ts[-6:-3]))
>>> d
datetime.datetime(2013, 3, 14, 7, 15, 23)
棘手的部分是 TZ 是可选的，无论您是添加/减去时间偏移还是在日期对象中设置时区。
