Found this too, thought I would post:
Code:
// This is an example of a UNIX timestamp for the date/time 11-04-2005 09:25.
double timestamp = 1113211532;
// First make a System.DateTime equivalent to the UNIX Epoch.
System.DateTime dateTime = new System.DateTime(1970, 1, 1, 0, 0, 0, 0);
// Add the number of seconds in UNIX timestamp to be converted.
dateTime = dateTime.AddSeconds(timestamp);
// The dateTime now contains the right date/time so to format the string,
// use the standard formatting methods of the DateTime object.
string printDate = dateTime.ToShortDateString() +" "+ dateTime.ToShortTimeString();
// Print the date and time
System.Console.WriteLine(printDate);
