You should read the error message, and try to understand what is meant with that.

Especially the line: "The Date header is invalid ..."

P.S. Its meaning is that the header (the one with 'Date:....') has an invalid date.

The valid options for this Date in het header of an HTTP message are described in some RFC's.

Chapter 14.8 (https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html)
The Date general-header field represents the date and time at which the message was originated, having the same semantics as orig-date in RFC 822. The field value is an HTTP-date, as described in section 3.3.1; it MUST be sent in RFC 1123 [8]-date format.
Date = "Date" ":" HTTP-date
An example is
Date: Tue, 15 Nov 1994 08:12:31 GMT

chapter 5.2.14 (https://tools.ietf.org/html/rfc1123#page-55)

That's why you should not change the date format wich is used in the header of a HTTP message.
