Calculate the difference between two dates/times with Javascript (1 post)

This functions computes the difference between two dates. Pretty simple usage, just pass the two dates as parameters when you call the function.

function dateDiff(laterDate,earlierDate) {
            var diff = laterDate.getTime() - earlierDate.getTime();

            var days_diff = Math.floor(diff/1000/60/60/24);
            diff -= days_diff*1000*60*60*24

            var hours_diff = Math.floor(diff/1000/60/60);
            diff -= hours_diff*1000*60*60

            var min_diff = Math.floor(diff/1000/60);
            diff -= min_diff*1000*60

            var sec_diff = Math.floor(diff/1000);
}
