Compare only the time portion of two dates, ignoring the date part

Question

What\'s a good method to, given two Date objects, compare the difference between their time portion only, completely ignoring Year, Month and Day?

It\'s quite the op

Answer 1

Dont know how good practiced or efficent is this one but i've written a simple function using the Date object that serves my purposes. It returns a true or false is the first date value bigger than the second. The inputs d1 && d2 are Date objects.

function CompareTimes(d1, d2) {
             if (d1.getHours() < d2.getHours()) {
                 return false;
             }
             if (d1.getHours() > d2.getHours()) {
                 return true;

             } else {
                 return (d1.getMinutes() > d2.getMinutes());
             }
};
