Time Zone retailed for $99.95 back in 1982 and, possibly due to said exorbitant price, didn't do that well saleswise. On the other hand, it was a huge and very interesting graphical/text-adventure by Roberta Williams and Online Systems (Sierra) that had gamers explore 7 time zones and 7 regions. It's also highly collectible.
Also here's the rare Time Zone (Apple II) on eBay for you to bid on. It's the boxed version of the game, that comes complete with all the disks and the manual. As an added bonus, you'll also be getting a copy of The Book Of Adventure Games.
