patch to rcstest (from RCS)

[rew]

On my machine the rcstest shell script failed because of a peculiarity in the
date(1) function.  When given the -u option (which it doesn't understand) it
not only prints an error message to stderr but also prints the local date to
stdout.  This causes the "date" variable to wind up with two dates in it.

The included patch fixes this.
