/**
* u-count-down 倒计时
* @description 该组件一般使用于某个活动的截止时间上,通过数字的变化,给用户明确的时间感受,提示用户进行某一个行为操作。
* @tutorial https://uviewui.com/components/countDown.html
* @property {String | Number} timestamp 倒计时时长单位ms (默认 0
* @property {String} format 时间格式DD-日HH-时mm-分ss-秒SSS-毫秒 (默认 'HH:mm:ss'
* @property {Boolean} autoStart 是否自动开始倒计时 (默认 true
* @event {Function} end 倒计时结束时触发
* @event {Function} change 倒计时变化时触发
* @event {Function} start 开始倒计时
* @event {Function} pause 暂停倒计时
* @event {Function} reset 重设倒计时,若 auto-start 为 true重设后会自动开始倒计时
* @example <u-count-down :timestamp="timestamp"></u-count-down>
