Second, yes, date is in GMT. All HTTP times are in GMT, and
I made a reference saying that the format is the same as for
Date: field and assumed that would be clear.
So what John Ellson said about giving exactly the same string
back in If-Modified-Since header as we got from Last-Modified
is valid, and in that sense we don't have to care about the
time zone, but since (for other reasons) Last-Modified is spec'd
to be GMT so is If-Modified-Since.

Use Expires: with the current time.
