No. Tor does TCP only. But tor-resolve (etc) uses TCP to transport the 
request to the exit server.

I'm not aware of any ntpd that allows use of SOCKS -- but why do you 
want an anonymously accurate clock, anyway?

Do what we all do .. test it. Fire up Ethereal and watch what happens. 
I'd bet you're successfully getting the IP via torDNS, and then directly 
connecting to the NTP server via UDP.

UDP is used for NTP becuase otherwise it'd be impossible to figure out 
the skew. You'd make that even more complicated than standard TCP by 
trying to send it via TOR. VPN'd udp/ntp dosen't even work so hot (but 
it does work).

If you really want an anonymous clock, hook up a GPS unit to a serial 
port and do it that way.
