我有一个脚本，它应该通过一个常数的值旋转（const旋转）。它应该从某个值和开始日期开始连续运行（const known）
列表中的下一个值应始终在30分钟后出现，但有一个例外：如果值的“id”是“193234”（Eldoren），则下一个值应该总是在60分钟（而不是30分钟）之后出现。
问题是，这个异常只对id“193234”的第一次出现有效，而不适用于后面的：

输出：

01:00 Skag
01:30 Pfliep
02:00 Magmaton
02:30 Eldoren // 1 hour until the next value, which is correct
03:30 Skag
04:00 Pfliep
04:30 Magmaton
05:00 Eldoren // should be 1 hour until the next value, too
05:30 Skag // so start should be at 06:00

这是我的脚本和JSFiddle：

$(function () {
          if ($("[id^=test]").length) {
            function addHours(date, hours) {
              var copy = new Date(date);
              copy.setTime(copy.getTime() + hours * 60 * 60 * 1000);
              return copy;
            }
    
            function addMinutes(date, minutes) {
              return new Date(date.getTime() + minutes * 60000);
            }
    
            function next(value) {
              return {
                index: (value.index + 1) % rotation.length,
                date: addHours(value.date, 0.5),
              };
            }
    
            const known = { id: 193210, ts: "2023-06-20T17:30:00" };
            const rotation = [

            ];

            const now2 = addHours(now33, 10);
            const now3 = addHours(now33, -0);
            const end = addHours(now33, rotation.length * 2);
    
            var cur = {
              index: rotation.findIndex((li) => li.id == known.id),
