solar measurement display in WD

I have the Hobby boards solar/temp/humidity unit working now with WD. All the sensors are being recorded but I have a question regarding solar measurements.
The WD graph is currently showing 1.2% and the main display is showing 1.2% 00.00hrs 0.5mm ET.
What do these readings mean and what do I need to do to make WD show hours?
It is currently 17:03 BST and very gloomy with mist and drizzle hence the 1.2% reading. It peaked around 17% earlier.
Thanks.
