Angular Time range slider

I am using http://danielcrisp.github.io/angular-rangeslider/demo/ to create a range slider but I would like it to use time(HH:MM) not just plain numbers. So it would range from 10m - 2hr. However I am a bit confused about how to achieve this.

Would I be better off formatting the time like this:

$scope.minTime = 10;
$scope.maxTime = 120;

The time is calculated in minutes then perhaps I could somehow maybe using the date filter convert the numbers into hh:mm but I would still prefer if it were formatted something like (10min, 30min, 1hr, 1hr 10min, 1hr 30min, 2hr)

Or is this a better way to do it:

$scope.minTime = 00:10;
$scope.maxTime = 02:00;

Or have I completely missed this and there is a better way?

The best options seems to be storing the values as minutes and displaying them using a custom filter.

<div ng-controller="myCtrl">
    <div range-slider pin-handle="min" attach-handle-values
         prevent-equal-min-max step="{{sliderConfig.step}}"
         min="sliderConfig.min" max="sliderConfig.max"
         model-min="sliderConfig.userMin" model-max="sliderConfig.userMax" 
         filter="hourMinFilter">
    </div>
</div>

app.controller('myCtrl', function ($scope) {
    $scope.sliderConfig = {
        min:  0,
        max:  120,
        step: 10,
        userMin: 0,
        userMax: 30
    };
});

app.filter('hourMinFilter', function () {
    return function (value) {
        var h = parseInt(value / 60);
        var m = parseInt(value % 60);

        var hStr = (h > 0) ? h + 'hr'  : '';
        var mStr = (m > 0) ? m + 'min' : '';
        var glue = (hStr && mStr) ? ' ' : '';

        return hStr + glue + mStr;
    };
});

UPDATE:

A modified version to allow a customizable filter max-value and show a different literal (by popular demand):

1) Extend the filter to receive a second argument: the max limit. 

...
return function (value, max) {
    if (value == max) { return 'All'; }

    var h = parseInt(value / 60);
    var m = parseInt(value % 60);
    ...

Note: The use of == instead of === is very important in order to check a string representation of the number against an actual number. If you want to avoid using ==, you should first convert both arguments to either String or Integer.

2) Modify the HTML to include the extra filter argument: 

<div range-slider pin-handle="min" attach-handle-values
     ....
     filter="hourMinFilter" filter-options="{{sliderConfig.max}}">
</div>
