Really interesting idea...but if you're right about the time matching the OS version, I think it should be something they adopted only recently...
...'cause I checked among the past official Apple PR images (I collect every single one of them since 1998) and the time displayed in the Mac OS X official screenshots doesn't match the OS version...althought we can say they all have something in common: "10.0 Cheetah"(March 2001), "10.1 Puma"(Sept 2001) and "10.2 Jaguar"(Aug 2002) screenshots share all the same time in the menubar: 11:23AM
