 Yea, it's something related to the new Fedora, didn't happen in previous
 olpc official releases. I tried to work on it but it looks like a gtk idle
 race thing as the original Clock developer decided to do the text
 rendering in a background thread (have been considering refactoring this
 out). When first enabled the text gets incorrectly centred based on the
 'what time is it?' string before the real time text is generated. It's
 centered correctly on the next redraw (each min, or if you show the date
 text).
