the problem comes up when I traced the problem when using kcmshell4 clock
to set timezone, which is when you changed timezone second time,
the setting just lost. I found the real problem is that
KDirWatch loses watch on /etc/localtime.
I can reproduce the watch lose very easily:
# inotifywait -m /etc/localtime
# zic -l Asia/Shanghai
# zic -l Asia/Muscat
# touch /etc/localtime
After Change timezone to Muscat, subsequent changes to /etc/localtime
won't be watched. because KDirWatch use inotify (I'm using a linux distro),
which monitoring file with respect to inode , not dir entry.
zic relinked ( hardlink ) /etc/localtime, so inotify just told attrib
change ( st_nlink change ) of the original file.
I post the patch a few months ago, and it seems that problem still exists
int KDE 4.3 RC, so I post here to see if it can make some help.
