You should be able to bracket the timeframe, but you will not be able to
get it exactly.

For the upper bound, the closest you can probably come would be the
second immediately before the first commit to the branch. You would want
to use one of the tools that plays with the 'cvs status' or 'cvs log'
output to find the first commit to the branch (cvs2cl is a good choice).

For the lower bound, you would want to take one second after the most
recent commit to the parent branch prior to the upper bound time found
in previous step.

For all practical purposes you should be able to use the upper bound
timestamp. Something like this may be what you want

   cvs2cl.pl --no-ancestors --follow branch-name --tags --branches \
     --revisions --chrono
   grep -B2 branch-name ChangeLog

If I have misremembered the syntax, I am certain that some one else on
the list will be able to help you.

        Good luck,
