如何将微秒转换为时间戳？ [英] How do I convert microseconds into a timestamp?
问题描述
我从一个未加密的.DAT文件中取出了这部分：
I took this piece from an unencrypted .DAT file:
代码：
00 e1 27 17 6f e6 69 c0
00 e1 27 17 6f e6 69 c0
这将转换为十进制的63,374,851,375,000,000。
Which translates to 63,374,851,375,000,000 in decimal. The units for the number are microseconds.
这个巨大的数字不能绕过1970年1月1日00:00:00格式；
And this huge number cannot bypass the 1st January 1970 00:00:00 format; such a format that most converters use today.
所以，是的。是否有使用1年1月1日格式的转换器？还是我该怎么做？
So, yes. Is there such a converter that uses the 1st January of the year 1 format? Or how shall I make one?
而且，时间戳记既是日期又是时间。
And by the way, a timestamp is both date and time.
推荐答案
您不会说自己使用的是哪种语言，如果它是.NET语言，则可以使用： http://msdn.microsoft.com/en-us/library/z2xf7zzk .aspx 对于该构造函数的输入以纳秒为单位（您确定您的数字以毫秒为单位，而不是以纳秒为单位吗？）。
You do not say what language are you using, if it is a .NET language, you can use: http://msdn.microsoft.com/en-us/library/z2xf7zzk.aspx for that constructor the input is in nanoseconds (are you sure that your number is in milliseconds and not in nanoseconds?).
以毫秒为单位，到纳秒的转换应该很容易：1毫秒= 1000000纳秒。
If you are sure it is in milliseconds, the conversion to nanoseconds should be easy: 1 millisecond = 1 000 000 nanoseconds.
但是我感觉那是十亿分之一秒，而不是毫秒...
But I have the feeling that those are nanoseconds and not milliseconds...
现在您已经告诉了我们以秒为单位 microseconds ：
Now that you have told us that it is in microseconds:
C＃示例从十进制到yyyy dd MM hh：mm：ss
C# Example from decimal to yyyy dd MM hh:mm:ss
long microseconds = 63370738175000000;
long ticks = microseconds * 10;
DateTime timestamp = new DateTime(ticks);
Console.WriteLine(timestamp.ToString("yyyy dd MM hh:mm:ss"));
打印：
2009 20 02 02:49:35
2009 20 02 02:49:35
从yyyy dd MM hh：mm：ss到小数的另一种方式
The other way around from yyyy dd MM hh:mm:ss to decimal
String dateString = "2009 20 02 02:49:35";
DateTime timestamp = DateTime.ParseExact(dateString, "yyyy dd MM hh:mm:ss",CultureInfo.CurrentCulture);
long ticks = timestamp.Ticks;
long microseconds = ticks / 10;
Console.WriteLine(microseconds);
打印：
63370694975000000
63370694975000000
如果要用十六进制表示，请输入：
And if you want it in hexadecimal just write:
Console.WriteLine(microseconds.ToString("X"));
然后它将打印：
E1234FB3278DC0
E1234FB3278DC0
