獲取當前時間

from time import strftime, localtime
local_time=strftime('%Y-%m-%d %H:%M:%S', localtime())

時間轉換成時間戳

import time
from datetime import datetime

time_stamp = int(time.mktime(
            datetime.strptime(my_time_str, "%Y-%m-%d %H:%M:%S").timetuple()))

時間戳轉換成時間

import time

timestamp = 1462451334

#轉換成localtime
time_local = time.localtime(timestamp)
#轉換成新的時間格式(2016-05-05 20:28:54)
dt = time.strftime("%Y-%m-%d %H:%M:%S",time_local)
 

獲取N天前或之後的日期

from datetime import datetime, timedelta

now_time = datetime.now()
#選擇要提前的天數n
change_time = now_time + timedelta(days=n)
#格式化處理
change_time_format = change_time.strftime('%Y-%m-%d %H:%M:%S')
