ISO19139 / ISO19115.3 / Index resource date fields as defined in the metadata.

[josegar74]

Previously the values were converted to UTC. If the timezone defined in the server is Europe/Madrid and the metadata has a creation date '2023-01-01T00:00:00', the index field creationYearForResource had the value 2022

Test case:

1. Create an ISO19139 and add a creation date 2023-01-01T00:00:00.

2. In the UI settings replace the Search application facet creationYearForResource with

  "creationYearForResource": {
    "terms": {
      "field": "creationYearForResource",
      "order": {
        "_key": "desc"
      }
    },
    "meta": {
      "collapsed": true
    }
  },

3. Go to the search page:

@fxprunayre, instead of extracting the year from the XML content, should we convert the date for these fields, not to UTC, but to the server timezone configured?

With the current change we are not dealing with metadata dates that have a timezone.

On the long run, we should probably rely on https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-datehistogram-aggregation.html#datehistogram-aggregation-time-zone, which means index in UTC and convert and format for a timezone

[fxprunayre]

We can go with that for the short term and investigate date histogram aggs later to better support when we have a mix of timezone
