I'm not sure how these get set/ updated but there are a fair number of weird dates in the PFS FAQ. Recently there are entries for 1/1/11 and 1/1/12 and several of these entries are marked as 'new' entries.
Apparently there was a mixup with the time machine. The entries from the future have been removed, and we are investigating to determine what the correct date should be for the ones marked 1/1/11.
