将ctime转换为unicode,将unicode转换为ctime python

Question

我已将ctime值转换为unicode

1295478503.6789999至'Wed Jan 19 18:08:23 2011'

我可以倒退吗？从第二行到第一行？

Answer 1

你想要Python时间模块,特别是strptime()函数.(你如何从ctime转换为unicode/string？可能是time.strftime().所以有必要寻找它的反方向,即time.strptime().)

以下是Google的一个很好的查询:http://www.google.com/search？q = python + expand + time + string

>>> t = time.strptime(u)
