This was on an upgraded 7.0 machine. The /etc/sysconfig/clock file on that

We're not sure where this came from (some config tool in 7.0?), but
ksconfig died on this file like this:

File "/usr/share/ksconfig/ksconfig.py", line 387, in ?
Apparently because EST is not a valid time zone (??). We don't know where

install, it works (ZONE="America/New_York") and after fixing the file on
the older machine, that works as well. Thanks.
