title: GPS Time to GMT time
body: <p>I have a millions of GPS data records that I wanted to use for some statistical analysis. Unfortunately there is a field called GPSTime that contains data like: 1320303210, 1318118326, 1302167205.</p>
  
  <p>I believe this is GPS date and time. Could any one assist on how to convert such numbers to normal timestamp (dd-mm-yyyy hh:mm:ss) </p>
