Two ways:
1a. If you also created a symbolic tag at the same time you created the
branch tag (which is what you should have done), then you just diff the
branch tag (which is the branch's current head) against that symbolic tag.
1b. If you did not create a symbolic tag, you can still create one based on
the date/time the branch was created (assuming you know exactly when you
created the branch). You can use 'cvs tag' or 'cvs rtag' with the -D (for
date) switch to create the symbolic tag.
2. Use the -D switch on the 'cvs diff' command to specify the date/time when
you created the branch as the starting point, and the branch tag as the
ending point. For example:
cvs di -D <date/time> -r <branch>
CVS accepts lots of different date/time syntaxes, but an easy one is:
"yyyy-mm-dd hh:mm:ss" (quotes are required because of the space between the
date and time). However, timestamps can be tricky. For example, time
stamps in CVS are usually given in UTC (for example in the case of a 'cvs
log' command), so if you want to do a diff using a date/time, you may find
that you have to specify the time according to your local timezone, and not
in UTC (as 'cvs log' gives). Assuming you can manage the timestamp issue,
you should have no trouble getting the diff you need.
