我制作了这个批处理文件，它可用作两个事件的计时器，并无限期地循环执行它们（直到您将其终止）。它还计算第一个事件所花费的时间加上第二个事件开始前所经过的时间。它将输出发布到文本文件中。计时器工作正常，但持续时间计算有时不太准确（但大多数情况下工作正常）。
问题：
如果计时器在凌晨 2 点（可能是凌晨 12 点，我当时还没有测试过）到上午 9:59 之间启动，则不会计算持续时间。相反，我会将第一个事件的最后停止时间发布到文本文件中两次。
有时，当我在早上运行计时器时，尤其是早上 5 点或 6 点左右，即使有开始和停止时间，持续时间也会计算为 00:00:00。有趣的是，计时器大多数时候都运行正常，并且只会随机产生此问题。
是否可以跳过一个事件的计时器并继续下一个事件而不终止批处理作业？ 如果是，怎么做？ 请发布示例代码。
有人能指出代码错误的地方并发布修复方法吗？拜托了。
