Script Preparation code:

var date = new Date();

var now = Date.now();
var nums = [];
for (var i = 0; i < 1000; i++) {
	nums[i] = now + i;
}

Tests:

new Date()
var len = nums.length; var d; for (var i = 0; i < len; i++) { d = new Date(nums[i]); }
setTime()
var len = nums.length; var d = reuse_date; for (var i = 0; i < len; i++) { d.setTime(nums[i]); }
