[BUG]

Describe the bug

Display logs in UTC instead of Browser time. In the current OFD logging stack is there any way to change the timezone to default UTC in code level as whenever we run the cluster setup job(basically will reatrt the opensearch) the OpenSearch dashboard timezone is selected as browser. Then we need to manually change the timezone to UTC which will be persisted only till the next cluster setup job.

Can we add this feature into the OFD logging stack?.

Actually, I also wanted to understand if there is a way to achieve this through configuration files, or if it can only be done via the UI?

@ravi96b after you made the change, can you do a additional check with dev tools for below request? make sure "dateFormat:tz": "UTC" exist in the search result.

GET .kibana/_search
{
  "query": {
    "term": {
      "type": {
        "value": "config"
      }
    }
  }
}

An example response

{
        "_index": ".kibana_4",
        "_id": "config:3.0.0",
        "_score": 3.7711172,
        "_source": {
          "config": {
             ...
            "dateFormat:tz": "UTC"
          },
          "type": "config",
          "references": [],
          "migrationVersion": {
            "config": "7.9.0"
          },
          "updated_at": "2024-10-15T10:05:53.211Z"
        }
      }

Hi @Hailong-am

The purpose is not validation; instead of making the changes every time from the OpenSearch dashboard (UI), we want to persist the change to dateFormat: "UTC". Therefore, we request guidance on how to achieve this in the configuration files.

Because the changes get reverted back to dateFormat:"browser time" after ofd restart .

I see, try this in your opensearch_dashboards.yml file, that will make it fixed as UTC and not able to change via UI.

uiSettings:
  overrides:
    "dateFormat:tz": "UTC"
