Did you realize that your binary data is the binary represantation of an OLE Automation date value?
So instead of getting long
, you should get a double
value from your array.
var b = new byte[8];
b[0] = 0x20;
b[1] = 0x64;
b[2] = 0xa8;
b[3] = 0xac;
b[4] = 0xb6;
b[5] = 0x65;
b[6] = 0xe4;
b[7] = 0x40;
var dbl = BitConverter.ToDouble(b, 0);
var dt = DateTime.FromOADate(dbl);
Console.WriteLine("{0:s}", dt);
Result is :
2014-05-14T17:00:21
I think the valid question should be: What is the equivalent of DateTime.FromOADate() in Java ?
Answer is:
public static Date fromDoubleToDateTime(double OADate)
{
long num = (long) ((OADate * 86400000.0) + ((OADate >= 0.0) ? 0.5 : -0.5));
if (num < 0L) {
num -= (num % 0x5265c00L) * 2L;
}
num += 0x3680b5e1fc00L;
num -= 62135596800000L;
return new Date(num);
}
