datetime.date.fromtimestamp:忽略小时和分钟

Question

以下代码返回'2012-06-07 00:00'时间戳1339119900000和1339120800000:

>>> from datetime import date
>>> date.fromtimestamp(1339119900000/1e3).strftime('%Y-%m-%d %H:%M')
'2012-06-07 00:00'
>>> date.fromtimestamp(1339120800000/1e3).strftime('%Y-%m-%d %H:%M')
'2012-06-07 00:00'

但是,这些时间戳相隔15分钟,而且它们都不是午夜.

我在Windows 7机器上运行32位Python 2.7.3,但在Red Hat机器上注意到了相同的情况.为什么这样,我如何从时间戳中获得小时和分钟的分辨率？

Answer 1

You are creating date objects, not datetime. Dates ignore all time information.

Use datetime objects instead if you want to preserve the time component:

>>> from datetime import datetime
>>> datetime.fromtimestamp(1339119900000/1e3).strftime('%Y-%m-%d %H:%M')
'2012-06-08 02:45'
>>> datetime.fromtimestamp(1339120800000/1e3).strftime('%Y-%m-%d %H:%M')
'2012-06-08 03:00'
