i'm ussing the below to see if a date (dd1) is in the future.  How do I change this to see if its in the future more than 2 minutes?  If its in the future but only by 2 minutes I want to say the date is valid but if its more than 2 mins in future then its invalid.  Thanks!

SimpleDateFormat ff = new SimpleDateFormat("MM/dd/yy HH:mm:ss", Locale.UK);
		         ff.setTimeZone(new SimpleTimeZone(0,"GMT"));
		 java.util.Date dd1 = ff.parse(strTimestamp, new ParsePosition(0));
		 java.util.Date dd2 = new java.util.Date();
			 System.out.println("future date detected");
			 return false;
