You can use a SimpleDateFormat http://download.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html to format it.

Date date = new Date(yourdate);
// format however you see fit
SimpleDateFormat format = new SimpleDateFormat("hh:mm:ss");
String formatted = format.format(date);

As suggested by Software Monkey, also use a SimpleDateFormat to parse your 24hr date if you don't already have it in millis.

Use two SimpleDateFormat objects - one to parse and the other to format the time.

Note also that 05:12:01 is not technically a 12 hour time (rather it appears to be an AM 24 hour time, given the lead 0 on the hour and the lack of a meridian designation). You probably want 5:12:01 PM.

It is possible that a 12 hour SimpleDateFormat will correctly parse a 24 hour time, provided that it is configured for lenient parsing. Just saying, so perhaps you need only one SimpleDateFormat.
