I'm not sure what you mean. Any product has to exist before it can be distributed. It doesn't have to exist before it can be marketed and sold, true, but it has to exist before it can be distributed. Can you rephrase that?

As far as I know, JMP (John's Macintosh Product) was designed and programmed by SAS Institute empoyees.

Isn't that a Macintosh convention? Microsoft Excel also has an option to use 1904 as the start date.
