Personally I would recommend using NTP over RDATE.  Your ISP is much more
likely to support NTP, as RDATE is pretty UNIX specific and is somewhat of
a security hole.  NTP comes with RH5 in the form of the XNTP3 rpm.  Whilst
you may not wish to go the whole hog and use full blown NTP, you can still
use the ntpdate program in the same way you would use rdate.

NTP is also far more accurate than RDATE, which may or may not be an issue
for you.

As for Windoze clients I use a little SysTray util called About Time,
probably available from TUCOWS, which uses SNTP (the equiv. of ntpdate) to
query any local NTP / TIMED servers you have running.
