Yes, I since the option format did not change, the timezone-03 -> RFC4075 
transition is quite simple. In fact, I have just did this and the updated 
version is available in the CVS repository. You can also go to the 
http://klub.com.pl/dhcpv6/snapshots/ and there you will find 
rfc4075-support directory. There are sources and Linux binaries. Of course 
you can download newest version from the CVS anyway.

As for OPTION_TIME_ZONE - well, it's obsolete, but I don't intend to 
remove support for it. However, if you don't like this option, you simply 
not configure it. Server provides only those options, which are configured 
AND are requested by clients. So you can safely just ignore that option.

No, I just know dibbler.

Great! Too bad I don't have access to VxWorks. I would be great to port 
dibbler to that platform.

Let me know if this works for you (especially if it doesn't).
