Okay … it's 2012 … and according to some people the world will end this year. However what's really happening? It's the mayan version of the Y2038 problem. While the signed 32 bit integer will send us to the 70ies on 03:14:07 UTC on Tuesday, 19 January 2038, the same happens on 22. December 2012. The mayan calender will send us from 13.0.0.0.0 to 0.0.0.0.0. And sorry, there is more potential in the Y2038 problem to kill us all as in the mayan calendar because nobody used the mayan calendar in embedded systems for nuclear weapons, nuclear power stations, isolation fields for strangelets created in the LHC (

) , air traffic control. With 32 bit signed integer i'm not so sure

As the mayan calendar is based on the factor of 20, there should be no reason why bak'tun should end on 13. I for myself am guessing thats because they were planning ahead for more than just the legislation period

happy new year!

From all what i've read 13.0.0.0 is already an invalid date

It are signed 32 bit integers that overflow in 2038. Unsigned 32 bit integers would last until 2106.

bigbrownpaperbagoverthehead you are right ...

calendar, not calender.

One of my favorite typos ... i know that a calender is something completely different

Also there is a 'colander.'

An Ultra-5 is not a nuclear weapon, but: take one, set the date in Solaris to something beyond January 19, 2038 and try to reboot, reinstall, whatever. This machine is broken, and can only be brought into life again with a lot of FORTH commands. I did this test in preparation of Y2k, some days ago.

I fear that also is the case for other machines based on the same or older NVRAM modules.. so I better set a reminder to back-date my old Ultras and Sparcstations a few days before Y2k38.. (at least the ones that won't be taken down by rust or dry caps decades before..)

Y2038 is so true, because you will not be able to show the effects on a personal device. All of them (phones, pc's, servers, tv's ...) will use 64 Bit time values, since nobody will look at a demonstration on a outdated 2018 or so machine.

But infrastructure devices and protokolls last a lot longer. I made some upgrades for a 1983 device in 1999, which has a good chance to be still in use today.

So you're looking for someone dumb enough not to notice that you have a maniacal tendency to go postal on your Exes?
