[lug] local timezone bad after update

[D. Stimits]

I did a massive yum update on a Fedora Core 2 box. Now the timezone is 
all messed up and I CAN'T make it do the right thing. If I tell my clock 
to display Denver time zone, it works right. If I tell it to use local 
time zone, it fails badly...I cannot, in any way, force or make it think 
local time zone is Denver...I think it is a bug because everything on 
the system says local timezone is Denver. Something is not right, 
setting it to local timezone should not be off by 3 hours (or 21 hours 
depending on how you look at it).

I use KDE, and the KDE menus and preferences all say that I am on Denver 
timezone, and that my clock on the cmos is set to local not to UCT. NTP 
is not enabled. /etc/sysconfig/clock says:
ZONE="America/Denver"
UTC=false
ARC=false

(what the heck is ARC?)

I'm at the point I want to find the responsible app and rewrite the code 
to never allow anything but local timezone = Denver, it's so frustrating 
to spend so much time trying to make this machine recognize that local 
timezone is Denver and that the cmos clock is not UCT. It only does this 
to me after updates on one machine and it always takes hours to figure 
it out, then I don't know what fixed it (some updates only show once a 
minute, which is when the clock updates the hour/minute part). What file 
can I manually edit to force this?
