Оператор Switch (javaScript) будет отображать только условие else

Я пытаюсь отобразить определенные строки в веб-приложении в определенное время в Великобритании. Это создало множество проблем, прежде всего, убедившись, что приложение отображает эти элементы во времена Великобритании, а не только там, где находится пользователь, и я подумал, что разобрался с этим.

Проблема, с которой я столкнулся, заключается в том, что Параметр switch отображает только оператор else и, похоже, игнорирует else if. Чехлы работают нормально.

Я уверен, что это что-то простое, но я не вижу этого. 

window.onload = function name() {
  var date = new Date();
  var d = date.getUTCDay();
  var t = new Date()
  var h = t.getUTCHours();
  var adjtime = (((new Date().getTimezoneOffset * -1) / 60) + h);
  var shows = [
    'String 1',
    'String 2',
    'String 3',
    'String 4',
    'String 5',
    'String 6',
    'String 7',
    'String 8',
    'String 9',
  ];
  var currentShow;
  var nextShow;

  switch (d) {
    case 0:
      if (adjtime >= 00 && adjtime <= 02) {
        currentShow = shows[0];
        nextShow = shows[5];
      } else if (adjtime >= 02 && adjtime <= 03) {
        currentShow = shows[5];
        nextShow = shows[6];
      } else if (adjtime >= 03 && adjtime <= 04) {
        currentShow = shows[6];
        nextShow = shows[0];
      } else if (adjtime >= 04 && adjtime <= 10) {
        currentShow = shows[0];
        nextShow = shows[3];
      } else if (adjtime >= 10 && adjtime <= 11) {

getTimezoneOffset - это метод, а не свойство, вам нужно вызвать getTimezoneOffset(), чтобы получить значение, 

var adjtime = (((new Date().getTimezoneOffset() * -1) / 60) + h);
...
