Date

The Date general HTTP header contains the date and time at which the message originated.

Warning: Date is listed in the forbidden header names in the fetch spec, so this code will not send the Date header:

js
fetch("https://httpbin.org/get", {
  headers: {
    Date: new Date().toUTCString(),
  },
});
Header type Request header, Response header
Forbidden header name yes
