but the "iburst" option, as useful as it might be, is meant to be
placed in the config file /etc/ntp.conf.  i was looking for an explicit
command-line option so that i could sync the system time *without*
having to mess with the config file first.

as deprecated as "ntpdate" might be, it at least had the virtue of
being self-contained.
