Description

The Expires header returned by /_uuids pretends that Jan. 1st 1990 was a Friday, while it was a Monday (http://www.timeanddate.com/calendar/?year=1990).

The HTTP parser in Akka detects this and warns about it:

[WARN] [04/28/2015 12:57:59.649] [canape-test-akka.actor.default-dispatcher-2] [ActorSystem(canape-test)] Illegal response header: Illegal 'expires' header: Illegal weekday in date 1990-01-01T00:00:00: is 'Fri' but should be 'Mon'
