I am trying to sort an array of objects with each object containing:

var recent = [{id: 123,age :12,start: 10/17/13 13:07} , {id: 13,age :62,start: 07/30/13 16:30}];

Date format is: mm/dd/yy hh:mm.

I want to sort in order of date with the most recent first. If date is same it should be sorted by their time parts.

I tried out the below sort() function, but it is not working:

recent.sort(function(a,b))

{

    a = new Date(a.start);

    b = new Date(b.start);

    return a-b;

});

Also how should I iterate over the objects for sorting? Something like:

for (var i = 0; i < recent.length; i++)

    {

        recent[i].start.sort(function (a, b)

        {

            a = new Date(a.start);

            b = new Date(b.start);

            return a-b; 

        } );

    }

There can be any number of objects in the array.
