Are you saying that the new KTimeZone and KDateTime classes don't meet your needs? If 
so, surely they could be modified. The only part that I am aware of that is still 
missing is cross-platform support, although there is skeleton provision for that. 
Nobody has yet volunteered code.

There are also new ICalTimeZone classs in libkcal. I hope to convert libkcal code to 
use use these classes sometime soon.
