Consider setting timezone to what the client asks for.

No, the result is computed on the assumption that we're in the zone
specified by the timezone setting.  This might be hard to wrap your head
around if you only test in GMT or GMT0BST zones --- try something where
the offset is never zero to get a clearer picture of what's going on.
