tag a cvs merge point later based on the merging date

Question

The scenario:

I've merged the most recent version of my development branch to the head a couple of weeks ago. I know I have to tag the merge-points but I forgot. The head already contains a couple of features(4-5) which haven't been released yet because they are not properly tested.

Plans have changed, now I must work on a brand new feature. This feature must be released with a subset of features from the head since we have not enough time to test and release them all.

The question:

I've already comitted a bunch of things to the head since merging. Is it possible to tag the merge-point of the head afterwards? If yes, HOW? I know the date and time of the merge exactly since I've commented the first commit after merging.

My plan:

merge the desired features from the head into my most recent branch(the same that I've merged to the head). Implement the brand new feature, test, release, merge back to head :)

You can create tags on files given a date with -D on cvs rtag.

$ cvs rtag -D DATE {module}

From Version Management with CVS:

-D date Tag the most recent revision no later than date.

Given the situation:

            tag_0     tag_1       tag_2     tag_3
------------|---------|-----------|---------|--------> TRUNK
    \
     \
      \----------------------> BRANCH

Let's say you want to merge modifications made from tag_1 until tag_3 from TRUNK to BRANCH. With a working copy in BRANCH branch, run this command:

$ cvs up -d -j tag_1 -j tag_3.

-d options creates new directories, if required.
