代码如下。求指导。

var later = require('later');
later.date.localTime();

console.log("Now:"+new Date());

var basic = {h: [8,9,10,11,12,13,14,15,16,17], s: [0,15,30,45]};
var composite = [
    basic,
    {h: [18], m: [0]}
];
var exception = [
    {dw: [6,7]}
];
later.date.localTime();
var schedule = {
    schedules:composite,
    exceptions:exception
};

later.date.localTime();
var sched = later.schedule(schedule),
//var sched = later.parse.recur().on(schedu),
      t = later.setInterval(test, sched),
      count = 5;

  function test() {
    console.log(new Date());
    if(count <= 0) {
      t.clear();
    }
  }
