HarmonyOS TaskPool三分钟超时机制

TaskPool三分钟超时机制，超时计算的逻辑是什么？下面的代码，经测试，可正常返回，并没有报错

@Concurrent
async function delayExecute1<T>(value: T): Promise<T> {
  let start = Date.now()
  while (Date.now() - start < 1000 * 60 * 4) {
    continue
  }
  return value
}

let task: taskpool.Task = new taskpool.Task(delayExecute1, 100); // 100: test number
taskpool.execute(task).then((value: number) => {}).catch((error: Error) => {});
