I recently collected an A340 from a paint input, approx 12 days, the batteries were disconnected prior to the input and reconnected at the end and the clock was reset to the correct time/date. Prior to dispatching I noticed the ECAM message WTB engaged carry out test (or something along those lines) had to do SFCC WTB engagement test on flap & slats to clear the message, so it's still there on the 340
