Sounds like a good idea to me. The initial value of this special
variable should probably be (CONSTANTLY NIL) where NIL returned by the
handler means that it declines to provide a timestamp - which would be
equivalent to returning (GET-UNIVERSAL-TIME). The handlers should
generally return universal-times, of course.

Something like that. Would you like to send a patch?

But even if the template itself hasn't changed you might fill the
template with different values each time it is called, isn't that the
whole purpose of HTML-TEMPLATE? Or am I missing something?

Cheers,
Edi.
