The clock plugin launches every second and because it is an internal
plugin, xfce4-panel shows a 1s wakeup.

It is possible to launch the clock every minute when seconds are
disabled, we just need to sync the first minute. I can take a look at
this when holiday starts, the clock needs some cleanups anyway ;).
