/etc/localtime is now a symlink, from which the chosen timezone name is easily readable via readlink(). /etc/sysconfig/clock is hence obsolete. Please drop any usage, or creation of it, if s-c-d is still using it. thanks!
I've changed s-c-date so that it only uses /etc/sysconfig/clock if /etc/localtime is not usable for this (e.g. isn't a symlink, points to somewhere outside of /usr/share/zoneinfo). The next version in Rawhide/F-18 should have this fixed. *** This bug has been marked as a duplicate of bug 824033 ***
