My question is pretty simple but I'll provide some extra details so that everyone knows what I'm talking about. In Kingdom Hearts (the original) in the Second District in Traverse Town, the Gizmo shop has some switches you can hit (after unlocking the platforms by using Thunder in the 3rd District, blah blah...). Anyway, after you do so, the clock in the Gizmo shop freezes at 6:54 and you get 2 postcards.

Anyway my point is: Why 6:54? Is it an Easter egg, a reference to something involving the creators (Square likes to do that sometimes), or is it just "lol 6-5-4"? I know it's not really a big deal but I was just wondering.
