Javascript 基于时间的值轮换

我有一个脚本，它应该在常量(const rotation)的值之间旋转.它应该从某个值和开始日期(const known)开始连续运行和启动

列表中的下一个值应该总是在30分钟之后出现，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，这个例外只适用于id"193234"的第一次出现，而不适用于后面的出现:

Output:个

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 playbook 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 = [
              { id: 193210, name: "Pfliep " },
              { id: 186827, name: "Magmaton" },
              { id: 193234, name: "Eldoren" },
              { id: 193149, name: "Skag" },
            ];
    
            const now33 = new Date();
            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),
              date: Date.parse(known.ts),
            };
    
            while (cur.date < now3) {
              cur = next(cur);
            }
    
            const out = document.getElementById("test");
    
            let increaseMinutes = 0;
    
            while (cur.date < end && cur.date < now2 && cur.date > now3) {
              const li = document.createElement("li");
              li.className = "test";
    
              var link = document.createElement("a");
              link.textContent = `${rotation[cur.index].name}`;
              link.href = "dadada";
              link.class = "dadada";
    
              li.innerText = `${rotation[cur.index].name} (${cur.date.toLocaleString()})`;
    
              var id = `${rotation[cur.index].id}`;
              var title2 = `${rotation[cur.index].name}`;
              var link = "https://de.wowhead.com/npc=";
              var ClassName = "weeklytext";

              var ClassName3 = "peinigertime";
    
              var options = { hour: "numeric", minute: "numeric" };
    
              var date33 = `${addMinutes(cur.date, increaseMinutes).toLocaleString("en-GB", options)}`;
    
              if (id == 193234) {
                increaseMinutes = 30;
              } else if (increaseMinutes > 0) {
                increaseMinutes += 0;
              }
    
              $(
