Note the revision numbers -- the changes were all on branches.

when I do:

That cvs diff with two dates only shows differences on the trunk.  This
is an unfortunate limitation; some commands let you specify both a
revision (branch) and a date, but diff isn't one of them.  There was
some discussion a few weeks ago about harmonizing the various ways of
specifying dates and revisions, but no concensus was achieved.
