Answer 1

You are working with a UNIX time stamp. First you need to convert it to an integer value, then go ahead and add that amount of seconds to the epoch (January 1, 1970).

Here is an example:

string hexValue = "529CD17C";
int secondsAfterEpoch = Int32.Parse(hexValue, System.Globalization.NumberStyles.HexNumber);
DateTime epoch = new DateTime(1970, 1, 1);
DateTime myDateTime = epoch.AddSeconds(secondsAfterEpoch);
Console.WriteLine(myDateTime);

Hope that was helpful!

Here is someone with the same question http://social.msdn.microsoft.com/Forums/en-US/c9624a19-1ef6-4f60-b063-527beb36de1d/hex-string-to-datetime-conversion It looks like the function provided could work.

They first convert the HEX value to an integer and then convert the integer to a date type.
