你可以从两个方向，unix epoch <==> datetime:

import datetime
import time


the_date = datetime.datetime.fromtimestamp( 1639763585 )



unix_time = time.mktime(the_date.timetuple())

assert  ( the_date == datetime.datetime.fromtimestamp(unix_time) ) & \
        ( time.mktime(the_date.timetuple()) == unix_time         )   

我使用ciso8601，它比datetime的strptime快62倍。

t = "01/12/2011"
ts = ciso8601.parse_datetime(t)
# to get time in seconds:
time.mktime(ts.timetuple())

你可以在这里了解更多。

>>> int(datetime.datetime.strptime('01/12/2011', '%d/%m/%Y').strftime("%s"))
1322683200

只需使用datetime.datetime.strptime:

import datetime
stime = "01/12/2011"
print(datetime.datetime.strptime(stime, "%d/%m/%Y").timestamp())

结果:

1322697600

要使用UTC而不是本地时区，请使用.replace:

datetime.datetime.strptime(stime, "%d/%m/%Y").replace(tzinfo=datetime.timezone.utc).timestamp()

你可以从两个方向，unix epoch <==> datetime:

import datetime
import time


the_date = datetime.datetime.fromtimestamp( 1639763585 )



unix_time = time.mktime(the_date.timetuple())

assert  ( the_date == datetime.datetime.fromtimestamp(unix_time) ) & \
        ( time.mktime(the_date.timetuple()) == unix_time         )   

我建议约会日期:

import dateutil.parser
dateutil.parser.parse("01/12/2011", dayfirst=True).timestamp()
