python利用时间戳计算时间差

主要是下面几步转化：

•  1.由时间戳到时间元组struct_time

t1=time.localtime(stamp1)

• 2.由时间元组到格式化时间字符串

 t1=time.strftime("%Y-%m-%d %H:%M:%S",t1)

• 3.由格式化时间字符串到datetime对象的时间

time1=datetime.strptime(t1,"%Y-%m-%d %H:%M:%S")

• 4.利用datetime的属性获取时间差

import datetime
def cal_time(stamp1,stamp2):
    t1=time.localtime(stamp1)
    t2 = time.localtime(stamp2)
    t1=time.strftime("%Y-%m-%d %H:%M:%S",t1)
    t2 = time.strftime("%Y-%m-%d %H:%M:%S", t2)
    time1=datetime.strptime(t1,"%Y-%m-%d %H:%M:%S")
    time2 = datetime.strptime(t2, "%Y-%m-%d %H:%M:%S")
    return (time2-time1).seconds
