Simple Java timer library

Question

I have need for timer code in Java with these features:

Setting pieces of codes (Runnable or something like it) to execute once after a specific delay (with second precision)
Changing the delay of an existing timer after the fact and cancelling timers.
Using a thread pool (so no java.util.Timer)

I've looked into using Quartz, but it appears to be simply too large.

Is there a smallish library that does this? Or can I actually use Quartz? Or how would I implement it myself, using ScheduledExecutor?

I didn't quite ask this question but the only thing you seem to want that Java timers aren't giving is thread pooling, and while I never got around to using the answers I got they seem to address that

Can I saturate a program with Timer objects?

Look at this post : Java Timer vs ExecutorService?

public <V> ScheduledFuture<V> schedule(Callable<V> callable,

                long delay, TimeUnit unit);

public ScheduledFuture<V> scheduleAtFixedRate(Runnable command,

                long initialDelay, long period, TimeUnit unit);

public ScheduledFuture<V> scheduleWithFixedDelay(

                Runnable command, long initialDelay,

                long delay, TimeUnit unit);

It's what I use now, but I need the ability to change the delay of existing timers to proceed. – Bart van Heukelom Apr 05 '11 at 11:08
@Bart : ok i understood that you want to change the delay dynamically. – Dead Programmer Apr 05 '11 at 11:26
