I'm a bit puzzled by an Olympic news item I've just heard.  Radio Scotland announced that there is to be a bell ringing throughout the country at twelve minutes past eight and that we are playing our part with an event at the Scotsman steps.  It seemed an odd time but after a moment's thought 2012 popped into my head.  Ah that's it I thought, but then the radio said it's this morning not this evening.

So what's it all about?
