So what's your working theory here, that the articles about the 787's not making the switch as well an the picture of the PFD with the date of 1999 are all fake?
Why would it be a fake??? As in my post, and as eppy also noted, the effect is the acquisition time of first fix. Your older system will still boot up, as will all the others, even the ones that show the date as 1990. It will just take a while to acquire the sats and database will be short..
