TestCase::compare doesn't print out dates' milliseconds

which makes it difficult to see why a comparison of two dates fails when only their milliseconds differ:

import QtQuick 2.0
import QtTest 1.0

TestCase {
    id: testcase
    name: "Test"

    function test_defaultConstructed() {
        var d1 = new Date(2000, 0, 1);
        var d2 = new Date(2000, 0, 1);
        d2.setHours(0, 0, 0, 1);

        print(d1, d2)
        compare(d1, d2)
    }
}

FAIL! : qtquickcontrols::Test::test_defaultConstructed() Compared values are not the same
