HarmonyOS TextTimer示例运行不正常

目前beta2往后的版本做了一次不兼容更新调整。TextTimer组件的使用需要根据定义的format属性来主动适配，调整回调参数的数量级。默认值是“HH:mm:ss.SS”，其中，毫秒可使用S、SS和SSS关键字表示，分别代表100ms、10ms和1ms。此时的elapsedTime 需要*10来表示ms级，即代码中config.elapsedTime/ 100，而不在是/1000。

https://developer.huawei.com/consumer/cn/doc/harmonyos-releases-V5/changelogs-for-all-apps-b031-V5#texttimer的ontimer回调频率与参数单位调整

示例参考：

class MyTextTimerModifier implements ContentModifier<TextTimerConfiguration> {
  constructor() {
  }

  applyContent(): WrappedBuilder<[TextTimerConfiguration]> {
    return wrapBuilder(buildTextTimer)
  }
}

@Builder
function buildTextTimer(config: TextTimerConfiguration) {
  Column() {
    Stack({ alignContent: Alignment.Center }) {
      Circle({ width: 150, height: 150 })
        .fill(config.started ? (config.isCountDown ? 0xFF232323 : 0xFF717171) : 0xFF929292)
      Column() {
        Text(config.isCountDown ? "倒计时" : "正计时").fontColor(Color.White)
        Text(
          (config.isCountDown ? "剩余" : "已经过去了") + (config.isCountDown ?
            (Math.max(config.count / 1000 - config.elapsedTime / 100, 0)).toFixed(1) + "/" +
            (config.count / 1000).toFixed(0)
            : ((config.elapsedTime / 100).toFixed(0))
          ) + "秒"
        ).fontColor(Color.White)
      }
    }
  }
}
