# print(time.localtime(time.time()-86400))                        #返回当地的时间戳
# print(time.strftime("%Y-%m-%d",time.localtime()))              #将struct_time转为字符串
# print(time.mktime(time.localtime()))                            #将struct_time   转为时间惟
# print(time.strptime('2016-03-12','%Y-%m-%d'))                 #将字符串，转为struct_time对象
