There is a statusbarclock app avail from maemo.org. I installed it but no clock appears in statusbarbar, so I think not compatible with OS2008 yet. Not only no clock, but it removed all apps from my desktop (and the osso-statusbar-cpu from the status bar.)!

I installed and tried the osso-statusbar-cpu you mentioned, technut, but clock is small and numbers nott bold enough for me old pirate eyes.
