The following JQuery Timers application knowledge from the JavaEye Forum
provides three functions
1. everyTime(time interval, [timer name], function formula name, [number limit], [wait for function program to complete])
2. oneTime (time interval, [timer name], function called)
3. stopTime ([timer name], [Function name])
