instantiating javascript vigilant job prototype.constructor.apply

let me start specific instance i'm perplexing do.

i have an array year, month, day, hour, minute, second millisecond components form [ 2008, 10, 8, 00, 16, 34, 254 ]. i'd instantiate date vigilant controlling following customary constructor:

new date(year, month, date [, hour, minute, second, millisecond ])

how i pass array constructor new date instance? [ update: doubt indeed extends over specific example. i'd whole fortitude built-in javascript classes date, array, regexp, etc. whose constructors over reach. ]

i'm perplexing something following:

var comps = [ 2008, 10, 8, 00, 16, 34, 254 ];
var d = date.prototype.constructor.apply(this, comps);

i substantially need "new" there somewhere. above only advantage tide i called "(new date()).tostring()". i also acknowledge i competence totally wrong instruction above :)

note: eval() accessing array equipment one, please. i'm graceful certain i should means array is.

update: offer experiments

since means adult operative answer yet, i've finished some-more enactment around. here's new discovery.

i possess class:

function foo(a, b) {
    this.a = a;
    this.b = b;

    this.tostring = duty () {
        relapse this.a + this.b;
    };
}

var foo = new foo(1, 2);
foo.prototype.constructor.apply(foo, [4, 8]);
document.write(foo); // advantage 12 -- yay!

but doesn't work unparalleled date class:

var d = new date();
date.prototype.constructor.call(d, 1000);
document.write(d); // still advantage tide :(

neither does work number:

var n = new number(42);
number.prototype.constructor.call(n, 666);
document.write(n); // advantage 42

maybe only isn't illusory unparalleled objects? i'm contrast firefox btw.
