I have watched the film again. About 1 hour 40 minutes into the film, while his higher functions are being cut, HAL is heard to say: "Good afternoon, gentlemen. I am a HAL 9000 computer. I became operational at the HAL plant in Urbana, Illinois, on 12 January 1992" - not 1997.
The story underwent numerous rewrites, and the plot varies between the film and the book. Small wonder HAL became psychotic - the first uncertainty it had to deal with was its age.
