The Age header is defined in RFC2616 as:

| 14.6 Age
|       The Age response-header field conveys the sender's estimate of the
|       amount of time since the response (or its revalidation) was
|       generated at the origin server.

Never attribute to malice what can adequately be explained by incompetence.
