Hi Al,
First of all: good thing you started off with Java, especially using Linux.
Just a tip. You do realize that Java has a Date class similar to the one
you've written, don't you? It's in the package java.util, docs are online
at:
http://www.javasoft.com/products/jdk/1.1/docs/api/java.util.Date.html
Good luck.
