python的time模块

 1 #encoding=utf-8
 2 import time
 3 
 4 # 返回时间戳
 5 print time.time()
 6 
 7 # 延迟运行单位为s,如下为延迟3s
 8 time.sleep(3)
 9 
10 # 转换时间戳为时间元组（时间对象）,自1970+second,其second为秒数
11 print time.gmtime(4)
12 
13 # 转换时间戳为本地对象
14 print time.localtime()
15 
16 # 将时间戳转换为字符串
17 print time.asctime(time.localtime())
18 
19 # 将时间戳转换为字符串
20 print time.ctime(5)
21 
22 # 将本地时间转换为时间戳
23 t = (2009, 2, 17, 17, 3, 38, 1, 48, 0)
24 print time.mktime(t)
25 
26 # 将时间对象转换为规范性字符串（常用）,格式如下
