When I wrote the above I was thinking about this, which is from the
dhcp-options man page:
option ntp-servers ip-address [, ip-address... ];
This option specifies a list of IP addresses indicating NTP (RFC
1035) servers available to the client. Servers should be listed in
order of preference.

The problem with this is that it does not solve the problem of making sure the
system clock has the correct valus in it before the install is done. Like the
op I do not like having the system report that it was installed in 1980 just
because I forgot to check to see if the clock was set correctly.

I think that if you have the ntp servers and TZ that should be enough info for
most installations. Am I missing something?
