Timer that resets

Hello,

My clan leader on a game I play asked if I could implement her a timer on our forums that would reset each time it reaches 0.

The timer would be in hours/minutes/seconds.

We want to use it to time the respawning rate of unique monsters in our game.

For example (to show you what I really am asking for), let's say one of the unique monster has a respawn time of 6 hours and 30 minutes. What I would want is a timer that countdowns from 6 hours and 30 minutes and 30 seconds (added the 30 seconds so it doesn't reset till we kill it which takes about 30 seconds) from when I set it up and when it reaches 0, I want the timer to reset to 6 hours 30 minutes and 30 seconds and countdown again and again and again.....

So, any ideas how to implement this?

I believe the forum is phpbb 2 if it helps.

No one has any ideas?

That's probably the best help you're going to get.
