1 import os 2 import time 3 from zipfile import ZipFile 4 5 zf = ZipFile('archive.zip', 'r') 6 for zi in zf.infolist(): 7 zf.extract(zi) 8 date_time = time.mktime(zi.date_time + (0, 0, -1)) 9 os.utime(zi.filename, (date_time, date_time))10 zf.close() time.mktime()函数执行与gmtime(), localtime()相反的操作，它接收struct_time对象或一个完整的9位元组作为参数，返回用秒数来表示时间的浮点数。
| Index | Attribute | Values |
|---|---|---|
| 0 | tm_year | (for example, 1993) |
| 1 | tm_mon | range [1, 12] |
| 2 | tm_mday | range [1, 31] |
| 3 | tm_hour | range [0, 23] |
| 4 | tm_min | range [0, 59] |
| 5 | tm_sec | range [0, 61]; see (2) in description |
| 6 | tm_wday | range [0, 6], Monday is 0 |
| 7 | tm_yday | range [1, 366] |
| 8 | tm_isdst | 0, 1 or -1; see below |
上述代码第8行就是构造该元组，(0, 0, -1)分别表示tm_wday,tm_yday,tm_isdst(-1表示夏令时未知)
