Date on iOS device returns NaN

Question

i'm currently developing a cordova web based application with ionic and angularjs. now i've created a service that returns a formatted time the way my client wants it.. the problem with this is that whilst it works on android and in browser, it displays NaN on an iOS device. The date i insert is from a database in timestamp : NOW() format, is there a fix for this? this is my date service:

.factory('displaydate',['$filter', function($filter) {
  return function (date){
    var maandarray = new Array('Januari', 'Februari', 'Maart', 'April', 'Mei', 'Juni', 'Juli', 'Augustus', 'September', 'Oktober', 'November', 'December'); 
    var actiondate = new Date(date);
    var today = new Date();
    if(today.getDate() == actiondate.getDate()){
        var hourssince =   today.getHours() - actiondate.getHours()
        var minutessince =   today.getMinutes() - actiondate.getMinutes()
        var secondssince =   today.getSeconds() - actiondate.getSeconds()
        if(hourssince > 0){
            date = hourssince+'u';
        }else if(minutessince > 0){
            date = minutessince+'m';
        }else{
            date = secondssince+'s';
        }
    }else{
        var oneDay = 24*60*60*1000; // hours*minutes*seconds*milliseconds
        var diffDays = Math.round(Math.abs((today.getTime() - actiondate.getTime())/(oneDay)));
        if(diffDays > 28){
            var identifier = actiondate.getMonth() - 1;
            var month = maandarray[identifier];
            date = $filter('date')(actiondate,"d ") + month +  $filter('date')(actiondate," yy " + " HH:" + "mm");
        }else{ 
            date = diffDays+'d';
        }
    }
    return date;
  }
}]);

Fixed this thanks to @Ian his comment ,

changed this:

var actiondate = new Date(date);

to this:

var t = date.split(/[- :]/);

// Apply each element to the Date function
var d = new Date(t[0], t[1]-1, t[2], t[3], t[4], t[5]);
var actiondate = new Date(d);
