如何将纳秒的纪元时间转换为人类可读的? [英] How to convert epoch time with nanoseconds to human-readable?
问题描述
我有一个以纳秒为单位的纪元时间戳 - 例如1360287003083988472
自 1970-01-01 以来的纳秒.
Python 日期时间对象和转换方法仅支持最高毫秒精度.
是否有一种简单的方法可以将这个纪元时间转换为人类可读的时间?
首先,将其转换为 datetime
具有第二精度的对象(落地,未四舍五入):
然后为了使其可读,使用 strftime()
返回的对象上的方法:
最后,加回纳秒精度:
<预><代码>>>>s += '.'+ str(int(1360287003083988472 % 1000000000)).zfill(9)>>>秒'2013-02-07 17:30:03.083988472'I have a timestamp in epoch time with nanoseconds - e.g. 1360287003083988472
nanoseconds since 1970-01-01.
The Python datetime objects and conversion methods only support up to millisecond precision.
Is there an easy way to convert this epoch time into human-readable time?
First, convert it to a datetime
object with second precision (floored, not rounded):
>>> from datetime import datetime
>>> dt = datetime.fromtimestamp(1360287003083988472 // 1000000000)
>>> dt
datetime.datetime(2013, 2, 7, 17, 30, 3)
Then to make it human-readable, use the strftime()
method on the object you get back:
>>> s = dt.strftime('%Y-%m-%d %H:%M:%S')
>>> s
'2013-02-07 17:30:03'
Finally, add back in the nanosecond precision:
>>> s += '.' + str(int(1360287003083988472 % 1000000000)).zfill(9)
>>> s
'2013-02-07 17:30:03.083988472'
