GPS Glitch Is Possible Tomorrow

Some older GPS devices might act a little weird on Saturday night. Any devices that rely on the 24 global positioning system satellites are going to turn back the clock at 7:59 p.m. Eastern time. When they designed the system in the 1980s, they only had enough storage space for a little more than a thousand weeks. On Saturday, they run out of space so it will reset itself by going back 20 years.
