United Airlines had problems with its "Easy Check-In" kiosks.
The South Carolina Department of Motor Vehicles "had a bug in one of the programs that calculates the date".These Leap Days occur on a reasonably regular basis, right? I seem to recall another one happening around four or five years ago. I've heard from a reasonably reliable source that we may even see another in my lifetime. They can't exactly be a surprise, can they?
Perhaps they should have tested more.
