I am a bit confused about creating a branch off old revision.

Basically I checked out a previous revision via "-D" option. Now I want to
create a branch and commit the change. I don't want it to merge with the
latest revision nor want to make change to the main trunc.

Unfortunately I kept getting sticky dates issue and I need help with correct
command to create a branch and commit the change in the repository for later
use.

Thanks in advance.
