1970: a year before the invention and widespread use of MP3s, PCs, or CDs. So why is it that my Rio S10 MP3 player thinks the date is January 1st, 1970, everytime I change the batteries? You would think it would at least set itself back to the date it was created, in 2002, not go back to a year before even its precursors had been invented. This is really annoying because I then have to go back through all of the years from 1970 to 2005 to reset the date.
The reason must be that Rio Audio is secretly developping a time portal back to the 1970s, and when they do, they want all of their devices to be compatible.
