如何將當前日期轉換爲紀元時間戳？

格式當前日期：

29.08.2011 11:05:02 

Answer 1

應該這樣做

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

使用strptime解析時間，並呼籲其time()獲得Unix時間戳。

Answer 3

假設你使用的是24小時時間格式：

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) 

Answer 5

Your code will behave strange if 'TZ' is not set properly, e.g. 'UTC' or 'Asia/Kolkata' 

So, you need to do below 

>>> 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 6

如果你想UTC嘗試一些 gm功能

：

import time 
import calendar 

date_time = '29.08.2011 11:05:02' 
pattern = '%d.%m.%Y %H:%M:%S' 
utc_epoch = calendar.timegm(time.strptime(date_time, pattern)) 
print utc_epoch
