这个类将覆盖您的需求，您可以将变量传递到ConvertUnixToDatetime并调用您希望它基于哪个函数进行操作。

from datetime import datetime
import time

class ConvertUnixToDatetime:
    def __init__(self, date):
        self.date = date

    # Convert unix to date object
    def convert_unix(self):
        unix = self.date

        # Check if unix is a string or int & proceeds with correct conversion
        if type(unix).__name__ == 'str':
            unix = int(unix[0:10])
        else:
            unix = int(str(unix)[0:10])

        date = datetime.utcfromtimestamp(unix).strftime('%Y-%m-%d %H:%M:%S')

        return date

    # Convert date to unix object
    def convert_date(self):
        date = self.date

        # Check if datetime object or raise ValueError
        if type(date).__name__ == 'datetime':
            unixtime = int(time.mktime(date.timetuple()))
        else:
            raise ValueError('You are trying to pass a None Datetime object')
        return type(unixtime).__name__, unixtime


if __name__ == '__main__':

    # Test Date
    date_test = ConvertUnixToDatetime(datetime.today())
    date_test = date_test.convert_date()
    print(date_test)

    # Test Unix
    unix_test = ConvertUnixToDatetime(date_test[1])
    print(unix_test.convert_unix())

如果datetime对象表示UTC时间，则不要使用time。Mktime，因为它假设元组在您的本地时区。相反，使用calendar.timegm:

>>> import datetime, calendar
>>> d = datetime.datetime(1970, 1, 1, 0, 1, 0)
>>> calendar.timegm(d.timetuple())
60

如果你想将python datetime转换为seconds since epoch，你应该显式地做:

>>> import datetime
>>> datetime.datetime(2012, 04, 01, 0, 0).strftime('%s')
'1333234800'
>>> (datetime.datetime(2012, 04, 01, 0, 0) - datetime.datetime(1970, 1, 1)).total_seconds()
1333238400.0

在Python 3.3+中，您可以使用timestamp()来代替:

>>> import datetime
>>> datetime.datetime(2012, 4, 1, 0, 0).timestamp()
1333234800.0

def datetime_to_epoch(d1):
"""
January 1st, 1970 at 00:00:00 UTC is referred to as the Unix epoch
:param d1: input date
:return: seconds since unix epoch
"""
if not d1.tzinfo:
    raise ValueError("date is missing timezone information")

d2 = datetime(1970, 1, 1, tzinfo=timezone.utc)
time_delta = d1 - d2
ts = int(time_delta.total_seconds())
return ts


def epoch_to_datetime_string(timestamp, tz_name="UTC", **kwargs):
"""
method to convert unix timestamp to date time string
:param ts: 10 digit unix timestamp in seconds
:param tz_name: timezone name
:param kwargs: formatter=<formatter-string>
:return: date time string in timezone
"""

naive_date = datetime.fromtimestamp(timestamp)
aware_date = naive_date.astimezone(pytz.timezone(tz_name))
formatter = kwargs.pop("formatter", "%d %b %Y %H:%M:%S")
return aware_date.strftime(formatter)

使用UTC时区:

time_stamp = calendar.timegm(dt.timetuple())

datetime.utcfromtimestamp(time_stamp)

解决方案是

import time
import datetime
d = datetime.date(2015,1,5)

unixtime = time.mktime(d.timetuple())
