Having made my first foray onto the list with a bold post, I now retract same.

Being the computer geek I am, I sometimes forget what is common knowledge and what is not. I was just a little sick of the "me too" posts on the Y2K thing and wanted to add a little DSM content. By the time I was done, I once again figured out a good prank for April 1 a few days too late (happens to me every year). I'm getting sick of the press overstating the Y2K problem. They often mention "planes falling from the sky" and "intersections with all lights green". As if there weren't a million other possible bugs in the software that control these insanely complex systems that could cause problems, right here, right now. At my day job, we have to certify that we are "Year 2000" compliant - huge amounts of paperwork - meanwhile, we have several other bugs in our code that we *don't* need to sign paperwork about... Just doesn't make too much sense to me. A bug is a bug - how come people don't go around talking about stack overflow problems in the same tone of voice? A lot of the problems surrounding Y2K problems involve the abbreviation of the year 19xx into just xx. Bytes don't overflow at 100 or 2000. They overflow at 256 or 65536, etc. Almost all computers since the invention of Unix seem to mark time as some number of seconds past a baseline like 1970 or 1980. These systems don't overflow years at nice round numbers - a lot of the Microsoft DOS stuff will roll at 2036 or 2047. As far as I know, there are currently *no* ECUs on the market that keep track of time. Most of them keep track of mileage if they are trying to stamp the error codes, or maybe seconds elapsed since car started. The problem is that the ECU could never have any concept of what time it really is unless the driver could update it somewhere. Also, I have yet to see a PC clock that didn't lose less than 3 seconds/day. Given the temperature extremes inside a car, I don't think it could be done easily. Even at a conservative 3 secs/day, you'd be +/- 3 hours at the end of ten years. Not really useful except for relative time. I thought the placement of the article after a Mac/Tandy love- note would tip people to the comment being phony. I guess my pointing it out at the top of the digest kinda backfired (no pun intended). Sorry if I scared anyone...
