Getting additional parameters from DHCP

Hi,

While being rather new to the Arduino I'm really enjoying my Arduino Duemilanove and Wiznet Ethernet shield. I've managed to get a few things working by going through the examples and other peoples code and it's great.

I'm now looking to get a bit more creative with it and build a nice little NTP clock like alot of others but I was hoping to get details like the UTC offset and NTP server IP from DHCP. Is this possible?

Thanks,
