双向转换为日期时间总是失败 [英] Conversion of double to datetime always fails

问题描述

我使用记事本打开Safari浏览器的History.plist文件，我发现访问的URL的编码日期时间是9位数+ DOT +一位数。我不知道如何将它解释为适合的日期时间格式，我希望将其更改为当前日期。

I open the History.plist file of Safari browser using a notepad and I find the encoded datetime of an accessed URL is 9 digits+DOT+one digit. I can't figure out how to interpret it to a suited datetime format, I wish to change it into the current date.

代码

DateTime dt=DateTime.FromOADate(348020617.0);

推荐答案

如果这是UNIX时间戳，那么可以转换使用此功能（借用 http://codeclimber.net.nz/archive/2007/07/10/convert-a-unix-timestamp-to-a-.net-datetime.aspx ）

If this is a UNIX timestamp, then you can convert using this function (borrowed from http://codeclimber.net.nz/archive/2007/07/10/convert-a-unix-timestamp-to-a-.net-datetime.aspx)

static DateTime ConvertFromUnixTimestamp(double timestamp)
{
    DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0);
    return origin.AddSeconds(timestamp);
}

为什么值得，你提到的时间戳（348020617.0）转换为01 / 10/81 @ 6:23:37 pm EST

For what it's worth, that timestamp you mentioned (348020617.0) converts to 01/10/81 @ 6:23:37pm EST
