I wouldn't mind if PX showed up and made the days a little longer. Seems I never have enough time... Wasn't it Lois Bujold (SF author) who said that her favourite planets always had longer days?

It'd bugger up all the telescopes though - nothing like a change of the length of the sidereal day to throw a spanner into your carefully tuned synchronization rigs.
