Cumulus Support

... one VP2 console knows how much rain there has been today, a man with two isn't quite sure!

The main console connected to Cumulus is reading 2.6 mm of rain today, my 'backup' console for experimentation is reading 2.4 mm, hmmm!
I guess a tip occurred really close to midnight.

Within 3 minutes, and the second console clock had drifted 5 minutes without Cumulus correcting it.
