Angular ng-repeat - limit results to timeframe - angularjs

Question

I have the following Model and would like to display the top voted over the last 24 hours
{
"_id": {
"$oid": "56abe20fabd3fa64187b5d21"
},
"user": {
"$oid": "56a1832a36dc3d0e00c7aa3f"
},
"title": "Intel Pentium i5 Quad-Core i5-6400",
"created": {
"$date": "2016-01-29T22:05:03.574Z"
},
"votes": 1
}
So basically limiting the ng-repeat to the created field within the last 24 hours.
Filter
angular.module('savings').filter('lessThan', function () {
return function(savings, requirement) {
var filterKey = Object.keys(requirement)[0];
var filterVal = requirement[filterKey];
var filtered = [];
if(filterVal !== undefined && filterVal !== ''){
angular.forEach(savings, function(saving) {
var today = new Date();
var date = new Date(saving.created.$date);
var diff = today - date;
diff = diff / (1000*60*60);
if(diff < filterVal) {
filtered.push(saving);
}
});
alert(filtered.length);
return filtered;
}
return savings;
};
});
Ive tried implement the answer below but it doesnt return any results.

I'll save you some time.. here is your filter.
app.filter('lessThan', function () {
return function(items, requirement) {
var filterKey = Object.keys(requirement)[0];
var filterVal = requirement[filterKey];
var filtered = [];
if(filterVal !== undefined && filterVal !== ''){
angular.forEach(items, function(item) {
var today = new Date();
var date = new Date(item.created)
var diff = today - date;
diff = diff / (1000*60*60)
if(diff < filterVal) {
filtered.push(item);
}
});
return filtered;
}
return items;
};
});
And call it like:
<div ng-repeat="item in items | lessThan: {'created':24}">
Here is a plunker.
EDIT: Based on the screenshot created property looks more like this:
"created": "2016-01-29T22:05:03.574Z"
I've edited the filter for this model
