Output RFC 3339 Timestamp in Java

// I want 2008-11-13T12:23:30-08:00
String timestamp = new SimpleDateFormat("yyyy-MM-dd'T'h:m:ssZ").format(new Date());
System.out.println(timestamp);
// prints "2008-11-13T12:23:30-0800" See the difference?

// Throws a ParseException
new SimpleDateFormat("yyyy-MM-dd'T'h:m:ssZ").parse("2008-11-13T13:23:30-08:00")

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'h:m:ss.SZ");
