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()

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。

我建议约会日期:

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

一个获取UNIX纪元时间的简单函数。

注意:此函数假设输入日期时间为UTC格式(请参阅此处的注释)。

def utctimestamp(ts: str, DATETIME_FORMAT: str = "%d/%m/%Y"):
    import datetime, calendar
    ts = datetime.datetime.utcnow() if ts is None else datetime.datetime.strptime(ts, DATETIME_FORMAT)
    return calendar.timegm(ts.utctimetuple())

用法:

>>> utctimestamp("01/12/2011")
1322697600
>>> utctimestamp("2011-12-01", "%Y-%m-%d")
1322697600

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         )   

你可以转换成等值格式

my_date = '2020/08/08'
my_date = my_date.replace('/','-') # just to adapte to your question
date_timestamp = datetime.datetime.fromisoformat(my_date).timestamp()
