I have a requirement for a very small piece of Flash for my own intranet. It's simply a timer - I'd like to have a Flash movie that when passed a start value for a timer in hours/minutes/seconds, would just carry on counting the seconds. I've written PHP that manages the whole setup and starting/stopping of the
timer(s), I just need to be able to display the current elapsed time in real time. Any ideas?

The interface would be something like:

Flash calls PHP like:

timer.php?timer_id=51

(because there are multiple timers, each with their own ID)

and gets a response like:

s_elapsed=1232

which is the elapsed time in seconds. Or it could return the value in HH:MM:SS format, whichever would be easier.
