Quick question, my playthrough just reached the end of 1966 and when I passed into 1967 the date indicator reset to 1966, so showing say 05/01/1967 as 05/01/1966. The future dates in the Alarm Clock all appear correct from 1967 and onwards, it's just the UT indicator in flight and when in the KSC/Tracking view. It shouldn't affect anything I guess since the UT in seconds seem normal, but I was wondering if someone saw this before?
EDIT - Looks like there is an offset in the calendar as the year did roll to 1967 once sufficiently into January. Perhaps it was always there but is slowly increasing over time so it is now more noticeable than before. I guess there's no problem then!
