Take a look at the Java Date, DateFormat, and SimpleDateFormat classes.  
Which of these you might want to use will depend on exactly what you want
the stamp to look like.  

If it would serve to put the date/timestamp into the file instead (rather
than in the filename) there's a slick mechanism that you can use:

ObjectOutputStream.writeObject(new Date());

which is then read back as follows: 

(Date)(ObjectInputStream.readObject());

and then you can parse the Date.
