如何在TaskPool和Woker里执行延时任务、周期任务

@Concurrent 
function printArgs(args: number): void { 
  console.info("printArgs: " + args); 
} 
 
let t: number = Date.now(); 
console.info("taskpool start time is: " + t); 
let task: taskpool.Task = new taskpool.Task(printArgs, 100); // 100: test number 
taskpool.executeDelayed(1000, task).then(() => { // 1000:delayTime is 1000ms 
  console.info("taskpool execute success"); 
}).catch((e: BusinessError) => { 
  console.error(`taskpool execute: Code: ${e.code}, message: ${e.message}`); 
})
