Package: gnome-panel
Version: 2.8.2-1
Severity: normal
clock-applet consumes way more CPU than it should, about 0.3% on my
600Mhz machine.

I strace'd it and it does the following over and over:

Why in the heck do you need to open, mmap, munmap, and close
/etc/localtime and /usr/share/zoneinfo/Universal every second? There
has *got* to be a more efficient way.
