It all depends on the program, I think. I know that Gentoo has 
an /etc/localtime that uses definitions of the time zone that you are in- and 
I got an update to "CST6CDT" that supposedly had the new 2007+ mappings in 
them. Programs all *should* use the /etc/localtime to tell the time from and 
with the right definition in /etc/localtime, it should go smoothly with just 
that one little update to change the whole system. It is programs that carry 
their own tables that becomes a problem. And then the programs have to NOT be 
updated/patched between now and the spring. I foresee this being a much worse 
problem with Windows programs with the tables hard-coded to prevent people 
from doing things like reset the system clock to use a shareware/trial past 
its expiration date. Those programs would have to be manually patched and 
redistributed to use the new time definitions. That would be more a vendor 
issue...and yet another reason to not use proprietary stuff if you can help 
it as you can't fix it. I haven't been burned on that particular issue by 
proprietary stuff, but a few other members here might remember a certain 
camera system with only cruddy binary drivers and a horrid Java control UI 
that gave me fits...
