Test runner

var x, i = 30;

for (; i !== -1; --i) {
	x = new Date(arrayDates[i][0], arrayDates[i][1], arrayDates[i][2], arrayDates[i][3], arrayDates[i][4], arrayDates[i][5], arrayDates[i][6]);
}

var x, a, i = 30;
for (; i !== -1; --i) {
	a = arrayDates[i];
	x = new Date(a[0], a[1], a[2], a[3], a[4], a[5], a[6]);
}

var x, a, i = 30;
for (; i !== -1; --i) {
	a = stringDates[i].split(rgx.datesplit);
	x = new Date(a[0], a[1]-1, a[2], a[3], a[4], a[5], a[6]);
}

var x, i = 30;
for (; i !== -1; --i) {
