VCR Plus codes are not Y2K50 compliant

Just in case those of you who still use your handy-dandy VCR codes in the TV listings opposite the comic page aren’t aware, there is some rather simple mathematics used in the creation of the “VCR Plus” codes which inhibit it from working after 2049 – this is a recreation of the logic:

    g_year_today = year_today % 100;
	if (g_year_today < 50)
		g_year_today += 100;
	if (g_year_today < 1900)
		g_year_today += 1900;

So, in a very similar to the Y2K issue, VCR+ assumes any year after [YY]50 is 2000+, and any before that is 1900+[YY] So, we have less than 32 years before we’ll have to set the clock back 100 years on our VCRs to record our shows using numerical shorthand.

I hope that together we can bring awareness to his issue and address it accordingly before airplanes are falling out of the sky, and VCRs are recording Jerry Springer against the owners’ wishes! Make your newspaper aware, even if they haven’t published these codes in at least eight years!
