What is the format, by default, for a date in the CSV file that is used in the "Upload CSV" option?

Many thanks

Elasticsearch does the actual date parsing, so it's based on the mappings. The Upload CSV wizard creates a date field with the default format, which is `strict_date_optional_time||epoch_millis`. You can more about the default format here: [https://www.elastic.co/guide/en/elasticsearch/reference/master/date.html](https://www.elastic.co/guide/en/elasticsearch/reference/master/date.html)

With "2015-06-30", its ok.

Many thanks.
