How to convert UTC time into local time in Java?

I have time coming from gpslocation service in 1352437114052 format. Can some one tell me how to convert this into local time either in Java or Matlab or Excel.

Answer

Create a new Date from your milliseconds since epoch. Then use a DateFormat to format it in your desired timezone.

Date date = new Date(1352437114052L);
DateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
format.setTimeZone(TimeZone.getTimeZone("PST"));
System.out.println(format.format(date));
