What would you like to do?
Javascript function to check if time has elapsed between two dates
// lastUpdate param should be a date object or a number representing milliseconds since 1970
// interval param should be seconds
// Interval is the elapsed time you are checking
// Returns true if the interval time has elapsed
// Returns false if the interval has not elapsed
function update(lastUpdate, interval) {
var curTime = new Date().getTime();
lastUpdate = (typeof lastUpdate.getTime == "function")? lastUpdate.getTime(): lastUpdate;
interval *= 1000;
curTime -= interval;
return (lastUpdate >= curTime) ? false: true;
}
// You could do more typechecking on the lastUpdate param if you are unsure of the data you are passing
