Description

A DateField object represents an HTTP Date header field. A Date field is an optional field that represents the date and time a request or a response message was originally sent. If you do not specify a Date field in a request message, then MATLAB® inserts one when you send it. For more information about this field, see RFC 7231 Semantics and Content, section 7.1.1.2 Date on the RFC Editor website.
