The Year 2038 Problem

As per Google's Usenet archives
[http://groups.google.com/googlegroup...ounce_20.html], the
first discussion of the Y2K problem on the Usenet was on January 18
1985 [http://groups.google.com/groups?thre...0%40reed.UUCP]. That
is a good 15 years before the problem manifested. Even then, it
turned out, we were scrambling for cover when the D-day was
approaching.

Although the Y2K scare turned out to be vastly overblown, we do have a
massive problem ahead of us ------ the Year 2038 problem. On Mon Jan
18 21:14:07 2038, the Unix seconds-since-epoch count will "roll-over".
After that, the time on the Unix systems will read as Fri Dec 13
14:45:52 1901.

IMHO, if we want to avoid the last minute panic that we witnessed
towards the end of the last millennium (while pursuing the Y2K
problem), we should begin the process of debating the viable solutions
to this problem NOW. It will take a long time for the consensus to be
built, and to come up with a solution that most (if not all) people
find acceptable. We also need considerable time to test out all
possible solutions in the real world, to decide if the solutions
really work as expected. We may also need to develop a suite of
recovery strategies should the problem manifest in some system on that
fateful Monday morning. All this takes time. So, as the late Todd
Beamer would have said: Let's roll.

[sarcasm on]
I believe that we should all go out and hunt down these old
Unix boxes and fix them. After all, this is way more important
than getting Windows to stop that Blue Screen of Death during
shutdown, holes in the security systems of servers and reduction
of spam.

No, No, No. These old Unix boxes should be replaced with the latest,
state-of-the-art hardware.
In 2038 these boxes will be as slow as 4.77Mhz x86 processors
from 1980's.


After all, there are at least 33 more years to develop a
good panic. It will probably take that long to find these machines
that are in charge of all the critical activities in the world.
See, smart people don't use machines that say programs have executed
illegal instructions (when it is the operating systems's fault).

Nope, stopping those Cell Phone spammers isn't as important because
these cell phones are not controlling critical systems (and I know
because I've either worked on them or seen them all).

So how will I panic, hmm, I don't know, but I've got a while to
figure it out. I think I will use my computer that requires
rebooting once a day, using appllications that can't communicate
with the operating system, even though they are made by the same
company. Yep, I search those web sites that will download spyware
onto my machine so they can see how I am panicking.

Yep, I've just added another item to my worry list. Someday,
I'll actually review it. :-)

It took ONE WEEK to verify that ALL systems were Y2K compliant.
No H1b visas were required!!!

The Y10K problem, when all those 4-digit years everyone is so proud of
become obsolete. If it took several years to fix just 40 years worth of
software for the Y2K problem, just think how long it will take to fix
8000 years worth of software for the Y10K problem. We had better get
started right away. There is no time to lose.

The entire planet's 3 thrillion barrels of oil is about 25% gone, and at the
current rate of 80 million/day, it will be completely gone within the lifespans
of some of the folks walking the earth today.

My solution is that I plan to be dead around 2040 or so.

No need to go into 'panic mode'.
There is time to resolve this issue
in a calm, cool and collected manner.
Certainly 64 bit processors and/or long long
data type will go a long way to resolving the issue.
But there will NOT be any need to import
thousands of H1b visas to fix this problem.
Y2K was definitely blown way out of proportion!
This was done by high priced consulting companies
trying to justify their worth.


Yes, no need to panic. What we need here a small team of specialists, gathered
together in a committee. Over the course of their lives, with the benefit of
government funding, I'm sure this top-notch group of problem solvers will come
forth with a resolution to our problem.

Wouldn't work, time isn't a constant. Doesn't show when your talking

I hereby nominate Bell Labs as the relative center of time, hence forth
referred to as the Origin. The time at which any event occurs is not
the local time, but the perceived time at the Origin "when" the event
occurred, even if the event was not "then" directly observable from the
Origin.

That depends on whether the system considers a time_t to be
signed or unsigned. Some UNIX systems consider the time range
of a traditional 32-bit time_t to be 1970 thru something like
2106, not 1901 thru 2038.


The obvious cure is to switch to the CP/M standard date format,
which is a 16 bit unsigned value expressing the count of days
since 1977-12-31. 0 is 'unknown'. This postpones the problem
until about 2157 or so.

Quite a good troll, he didn't need to prod it further.

The only reason it didn't happen was because we fixed it.

I don't recall you getting anywhere near my coffee machine or volkswagen.

Vastly overblown it was.
What was overblown was Joona's rhetoric, which was why I ignored it. I
presume you didn't see any dogs turning into cats, either. There were real problems. Most of them were fixed in time to ensure
your comfort.
I am quite sure I've heard stories about everything having an
electronic timer stopping working in 2000.

What's with the obsession about H1b visas then, eh?

There are plenty of existing "centers of time," and I might also mention
Greenwich. I'm suggesting a center not to be used as an actual point of
physical measurement, but as a conceptual reference point for use in
software.
