8 – How to get drupal time by REST GET HTTP

Is it possible to get Drupal 8 time with GET HTTP and REST?

I'm getting date format / entity / date_format / long

{
"uuid": "76e070cb-a783-47bf-89cc-db9f393a7d59",
"langcode": "en",
"status": true,
"Dependency": [],
"id": "long",
"label": "Long date by default",
"locked": false,
"model": "l, F j, Y - H: i"

}

But that 's not what I need. I need time to be able to sync a date to IoT.
