Time's Up: 2^30 Seconds Since 1970
An anonymous reader writes: "In Software glitch brings Y2K deja vu, CNET points out a small wave of Y2K-like bugs may soon hit, though it gets the explanation wrong. It will soon be about 2^30 (1 billion, not 2 billion) seconds since 1970 (do the arithmetic). Systems that use only 29 bits of a word for unsigned/positive integers, or store time as seconds since 1970 in this format, may roll back to 1970. (Many systems that do not need full 32 bit integers may reserve some bits for other uses, such as boolean flags, or for type information to distinguish integers from booleans and pointers.)"
This is the biggest computer-related time event since Y2K, which begun on January 1, 19100!
SOCIETY AS WE KNOW IT WILL COLLAPSE!!!! I have to get bottled water and batteries ready! This will be a complete disaster--just like Y2K!
Oops!
With some of the fashion's today (bell bottems, et al.)
this has been a problem since 1970. is it news that c-net realizes it?
If 1K = 1024 then Y2K is 2048. We still have a ways to go on that one! :)
I was born just before 1970.
I'm a billion seconds old.
Holy shit.
How many of you programmers are storing your years using 4 digits? Yeah, that's what I thought, all of you. What happens when it's January 1, 10000? Hmmm? Yes, that's right, your software will fail. It will roll back to 0, which wasn't even a year!
Now, I know what you're thinking. "There's no way someone will be using software I'm writing 8000 years from now." Yeah, and that's what programmers said 30 years ago about the year 2000. Be smart, and play it safe. Use a 5, or better yet, 10 digit year. What's a few bytes?
IIRC, bugger all went wrong. No nuclear weapons randomly fired off in any direction, no computers melted (well, none of mine)
So if your still using UnixWare, you may be in trouble.
So that means Linux is affected also, since its mostly copied from Unixware, right?
Its epoch is midnight 01-Jan-1904 and it uses an unsigned 32-bit integer to count seconds since then. That means it will run out at 06:28:15 09-Feb-2040.
:P
But, I'm sure Apple will have released a new Newton by then!
(I don't suppose anyone's ported the Rosetta writing recognition system to other PDA's, just in case?)
I plenty left over from Y2K. For those who did not prepare for Y2K and laughed at all the suckers who stockpiled and hid in bunkers, Ha! I will finally have the last laugh! - going into my bunker now....

You bought a Packard Bell too then huh?
maybe a midlife crisis is just our internal clocks rolling over.
Hmm, it seems that the date that a system's clock overflows is inversely proportional to the date that the system has outlived its usefulness
That does NOT count as a sufficient documentation of the above feature!
I shorted A31 to ground with a screwdriver on my Motorola MC68060 board. It blew a pullup resistor on an open collector output driver. Now A31 is always low -- and I'm too lazy to replace the tiny little 100 ohm surface mount. It runs just fine as long as I don't address high memory.
I just want to know: Does that count?
In standard /. fashion, I will overlook factual inaccuracies in the interest of pursuing my goal of correcting everyone's grammar. As such, I must tell you that Y2K *began* on January 1, 19100.
