Benchmark: Date methods: toISOString, getDay, constructor

Script Preparation code:

var date = new Date();
var dateString = date.toISOString();

function toISOString(date) {
	return date.toISOString();
}

function concat(date) {
 	var d = date.getDate();
	var m = date.getMonth() + 1;
	var y = date.getFullYear();
    var day = d <= 9 ? '0' + d : '' + d;
    var month = m <= 9 ? '0' + m : '' + m;
    var year = '' + y;
	return day + '-' + month + '-' + year;
}

Tests:

toISOString
for (var i=0; i<10000; ++i) { toISOString(date); }
concat
for (var i=0; i<10000; ++i) { concat(date); }
getDay
for (var i=0; i<10000; ++i) { date.getDay() }
new Date()
for (var i=0; i<10000; ++i) { new Date() }
new Date(string)
for (var i=0; i<10000; ++i) { new Date(dateString) }
