Huh? (TTG store order history hiccup)
 

It's a shame that couldn't been for a Back to the Future: The Game DVD.

Although I suppose it's still fairly appropriate considering the time traveling antics of "Chariots of the Dogs".

Heh-heh-heh
 

Obviously someone broke out the good bud.

They just like "69"

Oohhh, wash yer mouth oot with soap, yer wee ditry monkey.

Want to know what it really means?

The UNIX operating system (and variants) keep track of time as the number of seconds elapsed since midnight, January 1, 1970, in Greenwich Meridian Time. When you see December 31, 1969, it means they either most likely stored a -1 (negative one) in that slot (if they consider "-1" to mean the same as "invalid"), or a zero, and Telltale being in Pacific Time is behind GMT, so their zero is on that day. It's probably just a database hiccup returning a 0 or -1.
