Encounter's weather gadget getting the date (day) wrong

Hadn't noticed the problem before, but with snow and ice the last couple of days, I've been checking the weather a little more often... so I get slightly confused when the Weather Gadget tells me it's SATURDAY 4th December (and listing Sunday, Monday, Tuesday, Wednesday as its future forecast slots).

Luckily the actual forecast info seems to be the correct one for today/hour, but something inside the gadget is getting the day name wrong.

(and yes, my computer clock/date is correct etc)
