This was on an upgraded 7.0 machine.  The /etc/sysconfig/clock file on that
machine looked like this:

ZONE="EST"
UTC=false
ARC=false

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

Traceback (innermost last):
  File "/usr/share/ksconfig/ksconfig.py", line 387, in ?
    timeCombo.list.select_item(select)
NameError: select

Apparently because EST is not a valid time zone (??).  We don't know where
this ZONE entry came from, but something is not kosher.  On a clean 7.1
install, it works (ZONE="America/New_York") and after fixing the file on
the older machine, that works as well.  Thanks.
