Patch from Fillod Stephane:
* The "rdate.patch" file makes rdate to NOT settimeofday if the date to be set equals current date. This prevents the system from experiencing nasty time discontinuities caused by sub-second changes, with a protocol that has only over second resolution. Depending on your taste, the "fprintf(stderr..." may be removed.
