angular.module('myApp', [])
  .controller("myCntrl", function($scope, $filter) {

    $scope.isOpen = function(dealerSchedule) {
      var now = new Date();
      // 09:10AM - 06:30PM
      var times = dealerSchedule[Object.keys(dealerSchedule)[now.getDay() - 1]].replace(/(\d\d\:\d\d)(AM|PM)/g, '1/1/1900 $1 $2').split(" - ");
      var nowTime = new Date('1/1/1900 ' + now.toLocaleTimeString(navigator.language, {
        hour: '2-digit',
        minute: '2-digit',
        hour12: true
      }));
      return nowTime >= new Date(times[0]) && nowTime <= new Date(times[1]);
    };

    $scope.dealers = [{
