Ye Olde Airbus Clock is no more
"The validity of the WTB test is based on the calendar built into the a/c clock so adjusting the clock by more than 9 days will render the test log invalid - causing the slats and flaps to lock. Ordinarily the a/c clock runs with real-time updates off the GPS master clock and shouldn't be changed."
Who remembers when this used to be a thing?
Nice of Airbus to finally fix it.
Edit: I have heard a story or two about a hands on FO who once changed the clock in mid air causing flaps and slats to lock!
