You don't say which version of Solaris, but the config files should be the same.
However, NTP is *NOT* designed to be tested like that. It does *NOT* expect that
the clock will be pulled hither and thither, but only to follow small changes.
If you start jerking the clock about the results are at best unpredictable.

server Solaris1
driftfile /etc/inet/ntp.driftfile

If you want to add "restrict" statements you can do that later.

The startup (whether using /etc/init.d/xntpd on earlier versions or smf on 10)
should run ntpdate automatically, so you don't have to, and on the clients the
ntp daemon itself will not be started start until ntpdate completes, which
requires the server has locally synchronized so that ntpdate on the client can
get the time from it, which takes about 5 or 6 minutes. Use "ps -ef | grep ntp"
to check what is running on each system, and "ntpq -p" (see "man ntpq" under the
"peers" entry for the detail) to check things are working, and trust the output.
