I am. I think the we need a countdown. I Will see if i can get admin to set IT up a community countdown. Fear that all maemodevices Will transform into smoke machines and finally explode. You remember Y2K...right.

Way ahead of you:

well a calendar is much different than the internal "tick-tock" that is counting down rather than counting "continuance" so-to-speak.
"Calendrical" countdowns don't really exist either. The mayan (as well as other mathematical calendars) simply doesn't end. Going out of sync is likely . Reset may be necessary. Basing a calender on heavenly bodies moving is pretty exacting. Cogs within cogs...and all that...like clockwork gears. 2012 isn't actually the end of anything. Just a herald ...to a new tick-tock-ing. 'tween 2012 and 202? (can't recall exact year) allll the ancient mathematical calendars end (for reset and recalibration). What the new tick-tock will be and how conducive to human interests is another thing. Ages come and go...Cycles come around. More interesting is how the clock will chime...won't carry on with talk of gnostic studies ...I'd fill pages.
Silly calendars are like the gregorian(was it? can't remem.) which came before the julian (current) it was a mess...changing to the Julian had people believing they had lost a huge chunk of time from their lives....the riots were silly...lasted a long time throughout Europe. The Julian makes sense since it accommodates the leap year...no extra or lack of days in a year...(even still the Julian although perfect as perfect can be...is running out of sync with the natural cycle of the seasons now...)
The silliness of the internal unix countdown is a wee bit more interesting though. Since it really wasn't built with a deliberate ability to "tweak" it or recalibrate, reset, whatever. Awfully silly really. And it is more of a "tock-tick" than a "tick-tock" counting down rather than counting up...
I'm sure someone will find a solution..failing that I doubt it will throw the world into ruins... credit card debt restructuring may possibly be needed...alot of people out there may end up owing a lot more money afterwards.

No matter what clock/calendar you use, end is near (no shortage of apocalypticists, jesus being the major one, from our pov, or interpret: leave your father and mother behind, as anti-abortion/pro-family as the current reading tells us (also something about returning with witnesses of the crucifixion still alive to rewitness))

but to avoid touchy subjects and answer OP:
what will happen after 2036?
2037

OMFG! First Jolla, now this. Can really no one get a blooming countdown right?

(Hint: check the alleged versus real days, minutes etc format)

Apo's have come and gone for soo many cultures and civilizations...it isn't even funny.
Math though....math is eternal...
Best way of finding out is as has been suggested set the calendar to Dec. 31 2036 and see...
I doubt much will happen.
not for the nxx0 devices anyway.
The interaction of so much other tech and programs that will be affected and those spinoff ramifications...that ...however...that is another matter completely.
Not much can stop that literal internal countdown that unix is heading towards...I'm sure someone will come up with something sometime.

timezones are hard (srsly, work in a bank from the top tier, my requests since my country changed time to winter one were all showing 1h ahead, now fixed, i guess US caught up), good catch

Hum ....
well perhaps I am wrong...

possibly we will have issues with the durn billion-second-bug(calling it that but really it isn't a bug...but deliberately designed)-countdown.

Ach ...anyway I always wanted to live in the turn-of-the-century....epic time period.
Hang on to your nxx0 tight...the last best thing it may do is transport you back in time...get a crack at hitler, musso, and a few others while were at it.
P.S. don't bother taking your charger with you...take the solar instead

Actually, I wasn't on about time zones. The format is supposed to be yy:dd:hh:mm:ss, i.e. double digits everywhere. But the actual time is displayed with single digits if hours, minutes or seconds are less than 10. 23:65:4:35:1 just looks odd.
