>>> import datetime
>>> import time
>>> int(time.mktime(datetime.date.today().timetuple()))
1299427200

还有更简单的办法么？

@Livid oh, sry, didn't notice you need time for the day...
Then probably yours is the easiest way already :(

抱歉我没有表述清楚。

是希望获得今天 0 点时候的 timestamp。

貌似用calendar.timegm更好，mktime会返回浮点数，而且时区可能有问题。不过也没什么能简化的。

def mid_night_timestamp():
timestamp = int(time.time())
if timestamp % 86400 == 57600: //57600 = 86400 + (60 * 60 * -8)
return timestamp
else:
return timestamp / 86400 * 86400 + (60 * 60 * -8)

This is faster :D
不过仅在时区固定的时候有效，替换一下时区offset就可以了。如果在TimeZone aware的环境，需要用tzinfo的offset修改一下。

@keakon 嗯，确实应该在服务器端保存 UTC 时间。

感谢！！！
