Version: (using Devel) OS: Linux Installed from: Compiled sources KDE 3.x sorted the clock tooltip by offset. The plasma digital clock in KDE 4.2 should do the same. p.s. Thank you for getting >1 tz in the tooltip at all!!! Now I can feel good about upgrading someday...
+1 KDE 4.2 has a similar problem - Please make it sortable by "Region"
