6x的时间计算plainless一直warning getMillisOfSecond is deprecated

最近做搜索需要加入时间衰减公式，但是会一直被ES丢warning

 returned 1 warnings: [299 Elasticsearch-6.5.2-9434bed "Use of the joda time method [getMillisOfSecond()] is deprecated. Use [get(ChronoField.MILLI_OF_SECOND)] instead." "Mon, 06 May 2019 02:32:34 GMT"]

那么问题就来了，不能这样用了```value.millisOfSecond```新版的应该怎么调用？
相关公式：

"sort": [

    {

      "_script": {

        "script": {

          "source": "1000 * 3600 * 7 * 24 * 0.8 *((1 - params.factor) * _score)/(System.currentTimeMillis() - doc['publishDate'].value.millisOfSecond + 86400000 * 7 + 1) + (1 - (1 - params.factor) * (_score))",
