我的纪元以来有以下时间戳:
Timestamp
1346114717972
1354087827000
如何将这些时间戳转换为某种特定的输出格式,例如mm/dd/yyyy hr:min:sec
?
我尝试将它们转换为datetime.datetime
,但失败了:
>>> datetime.datetime.fromtimestamp(1346114717972)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: timestamp out of range for platform time_t
我该怎么做?

我会使用time
模块
>>> import time
>>> time.gmtime(1346114717972/1000.)
time.struct_time(tm_year=2012, tm_mon=8, tm_mday=28, tm_hour=0, tm_min=45, tm_sec=17, tm_wday=1, tm_yday=241, tm_isdst=0)
时间戳除以1000,因为您提供的戳记自纪元以来毫秒,而非秒数
然后使用strftime
格式如此
>>> time.strftime('%m/%d/%Y %H:%M:%S', time.gmtime(1346114717972/1000.))
'08/28/2012 00:45:17'

假设毫秒分辨率:
import datetime
s = '1346114717972'
fmt = "%Y-%m-%d %H:%M:%S"
# local time
t = datetime.datetime.fromtimestamp(float(s)/1000.)
print t.strftime(fmt) # prints 2012-08-28 02:45:17
# utc time
t_utc = datetime.datetime.utcfromtimestamp(float(s)/1000.)
print t_utc.strftime(fmt) # prints 2012-08-28 00:45:17

这是我见过的最简单的方法 -
$ python
Python 2.7.5 (default, Nov 6 2016, 00:28:07)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import time
>>> print(time.strftime('%Y-%m-%dT%H:%M:%S %Z',time.localtime(time.time())))
