There are a few requests to export timezone in order to be able to find the local timestamp. For that, we think the best option would be to export also the timezone (optionally) in the event, and make sure the @timestamp is always sent in UTC.

It still needs to be discussed what it's the best option to enhance the event with the timezone field, using a processor or a configuration option (maybe under the Elasticsearch output?).

Related to this, the following PRs were created by the community: #3622, #3743
