Try this

    function validate(dt1, dt2)
    {
        var jdt1 = Date.parse('20 Aug 2000 ' + dt1);
        var jdt2 = Date.parse('20 Aug 2000 ' + dt2);
        var diffMs;
        var diffMins

        if (isNaN(jdt1))
        {
            alert('invalid start time');
            return false;
        }

        if (isNaN(jdt2))
        {
            alert('invalid end time');
            return false;
        }

        if (jdt1 > jdt2)
        {
            diffMs = (jdt1 - jdt2);

            diffMins = Math.round(((diffMs % 86400000) % 3600000) / 60000); // minutes

            alert('start is greater by ' + diffMins + ' minutes');
        }
        else
        {
            diffMs = (jdt2 - jdt1);

            diffMins = Math.round(((diffMs % 86400000) % 3600000) / 60000); // minutes

            alert('start is less equal by ' + diffMins + ' minutes');
        }

        return true;
    }

Youre welcome. I also added return true since you were not doing that.
