Going completely off-topic now:
When I started as an intern, the first thing they gave me was the book "Clean Code" – and at that point I already had ten years of programming experience. If you're going for making this your profession you really wanna read similar books ... even if you have to do it in your free time. The sooner you learn how to write quality code the easier it will be to take it in.
As for your task: What exactly is your task? A timer that goes from 0 to 60 or from 60 to 0? Does it have to have tenths of seconds? Should it just repeat itself when it reached the end?
