The prediction made in the last blog entry was a little wide of the mark, and having been busy with other projects I didn't get round to making the small change to the software until today.
At about 4 o'clock this afternoon I shut down the polly system, at which point it was showing an up time of 673 days, 4 hours and 27 minutes.
I soon had the new version installed and I also took the opportunity to upgrade all the other software on the Raspberry Pi.
How long will this version run, before I think of another change? Or perhaps a hardware failure or a power cut will stop it first.
