Review comment:
To my understanding by default Elasticsearch only supports `date` field
type
https://opendistro.github.io/for-elasticsearch-docs/docs/sql/datatypes/#date-and-time-types
```
...
By default, the Elasticsearch DSL uses the date type as the only date-time
related type that contains all information of an absolute time point.
...
```
For the SQL endpoint, we can use date functions that will return other
date/time types out of them
