Question

如何将当前日期转换为纪元时间戳？

格式化当前日期:

29.08.2011 11:05:02

Answer 1

应该这样做

import time

date_time = '29.08.2011 11:05:02'
pattern = '%d.%m.%Y %H:%M:%S'
epoch = int(time.mktime(time.strptime(date_time, pattern)))
print epoch

Answer 2

如果"TZ"设置不正确,例如"UTC"或"Asia/Kolkata",您的代码就会表现得很奇怪

所以,你需要在下面做

>>> import time, os
>>> d='2014-12-11 00:00:00'
>>> p='%Y-%m-%d %H:%M:%S'
>>> epoch = int(time.mktime(time.strptime(d,p)))
>>> epoch
1418236200
>>> os.environ['TZ']='UTC'
>>> epoch = int(time.mktime(time.strptime(d,p)))
>>> epoch
1418256000

Answer 3

假设您使用24小时时间格式:

import time;
t = time.mktime(time.strptime("29.08.2011 11:05:02", "%d.%m.%Y %H:%M:%S"));

Answer 4

import time
def expires():
    '''return a UNIX style timestamp representing 5 minutes from now'''
    return int(time.time()+300)
