We have previously used C6k/Sup720 running SFX for this. I just tested a
3560 running 12.2(58)SE1 IP Services and it works fine.

I actually just tried a regular IP Base switch (also 12.2(58)SE1) and it
also answers to "ntpdate -q", even without "ntp master".

On that note: Use "ntp access-group peer <X>" to limit who can talk NTP
with the switch. I haven't been able to limit who can query and who can
serve via the "query-only" and "serve-only" keywords. I just don't
understand how it's supposed to work.
