That's why branch point tags are used.. to eliminate this ambiguity.

What _should_ have happened when this was tagged was:
 cvs rtag wollman_pending_bp sys
 cvs rtag -r wollman_pending_bp -b wollman_pending sys
 cvs checkout -r wollman_pending sys

And later, we could all do a:
  cvs [r]diff -r wollman_pending_bp -r wollman_pending
and clearly see what you are working on.

re: cvs's parsedate.y.. If anybody wants to fix it to understand all rcs's
forms of date coding, be my guest. :-)  I'm sure either Nate or I can take it
back to the cvs developers and check it into the current source.  Since CVS
uses local time by default and RCS uses GMT, one has to be careful. I usually
use something like: "3/31/96 10:00:07 GMT", but again one has to reverse the
month and date into the "backwards" system the americans use. :-)
Remember, to cvs, "april 1" covers a 24 hour time span, depending on where you
are in the world.

Cheers,
