Date fifteenLater = new Date(System.currentTimeMilllis() + (100*60*60*15));

Oops - typo
Date fifteenLater = new Date(System.currentTimeMilllis() + (1000*60*60*15));

you use the Calendar class to do any date arithmetic, you'll find an example here

You can save the original 'now' if you need it as a reference. The following prints

Tue May 05 11:04:14 BST 2009
Tue May 05 11:19:14 BST 2009


on my system
        Date now = new Date();
        Date fifteenLater = new Date(now.getTime() + (1000L*60*15));
        System.out.println(now);
        System.out.println(fifteenLater);

I believe the best way is to use Calendar class. Of course you can use Date or directly using System. See examples in the code below.
			// Using calendar calss
			GregorianCalendar now = new GregorianCalendar();
			now.add(Calendar.MINUTE, 15);
			Date fifteenMinutesAway = now.getTime();
			long fifteenMinutesAwayInMilliseconds = now.getTime().getTime();
 
			// Using Date or System.currentTimeMillis()
			Date date1 = new Date(System.currentTimeMillis() + 15 * 60 * 1000);
			Date date2 = new Date(new Date().getTime() + 15 * 60 * 1000);
