以YYYYmmddHHMMSSfraction格式查找日期之间的差异

Question

我有两个这样的时间戳:它们的格式为:YYYYmmddHHMMSSfraction

t1=20131229135931664000
t2=20131229140021638000

如何以秒为单位找到时间戳的差异?

Answer 1

解析datetime.datetime.strptime():

import datetime
format = '%Y%m%d%H%M%S%f'
dt1 = datetime.datetime.strptime(str(t1), format)
dt2 = datetime.datetime.strptime(str(t2), format)
difference = (dt2 - dt1).total_seconds()
