问题描述
要在 JavaScript 中获取时间戳,我们使用
To get timestamp in JavaScript we use
var ts = new Date().getTime()
到目前为止,将其转换为 Python datetime
的正确方法是什么,我使用以下代码
What is the proper way to convert it to a Python datetime
so far I use the following code
>>> jsts = 1335205804950
>>> dt = datetime.datetime.fromtimestamp(jsts/1000)
>>> dt
datetime.datetime(2012, 4, 24, 0, 30, 4)
我将时间戳除以 1000,因为我得到了类似的错误
I divide timestamp by 1000 because I get error like
ValueError Traceback (most recent call last)
1 d = datetime.datetime.fromtimestamp(a)
ValueError: year is out of range

推荐答案
你当前的方法是正确的,除以 1000 是必要的,因为你的 JavaScript 以毫秒为单位返回时间戳,而 datetime.datetime.fromtimestamp()
需要一个以秒为单位的时间戳.
Your current method is correct, dividing by 1000 is necessary because your JavaScript returns the timestamp in milliseconds, and datetime.datetime.fromtimestamp()
expects a timestamp in seconds.
为了保持毫秒精度,您可以除以 1000.0
,因此您使用浮点除法而不是整数除法:
To preserve the millisecond accuracy you can divide by 1000.0
, so you are using float division instead of integer division:
>>> dt = datetime.datetime.fromtimestamp(jsts/1000.0)
>>> dt
datetime.datetime(2012, 4, 23, 11, 30, 4, 950000)
