微信小程序van-datetime-picker打开后设置默认时间如：当天

<van-field size="large" readonly bind:tap="openPicker" is-link required label="到达时间"  error-message="{{arriveTimeError}}" model:value="{{arriveTime}}" bind:focus="arriveTimeFocus" bind:blur="arriveTimeRules"></van-field>
          <van-action-sheet title="选择到达时间" show="{{ show }}" bind:close="onClose" >
            <van-datetime-picker type="datetime"  bind:cancel="onCancel"
              bind:confirm="onConfirm" value="{{currentDate}}"  />
            </van-action-sheet>

data: {
    arriveTime: '',
    currentDate:new Date().getTime()
  }
  //关键点在currentDate:new Date().getTime()
//和 van-datetime-picker 的value="{{currentDate}}"这个属性
