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

if you just want to compare the time part of the dates then this would give you the right result -

public long compareTimes(Date d1, Date d2)
    {
        long     t1;
        long     t2;
        t1 = d1.getHours()*60*60+d1.getMinutes()*60+d1.getSeconds();
        t2 = d2.getHours()*60*60+d2.getMinutes()*60+d2.getSeconds();
        long diff = t1-t2;
        System.out.println("t1 - "+t1+", t2 - "+t2+",  diff - "+diff);

        return diff;
    }
