Posted: Sun Mar 10, 2013 11:28 pm Post subject: The Year 2038 UNIX BUG
Why 2038?
Our 32-bit root servers currently use the FreeBSD 4.7 operating system. As with all Unix and Unix-like operating systems, time and dates in FreeBSD are represented internally as the number of seconds since the UNIX Epoch, which was the 1st of January 1970 GMT.
32-bit systems can only store a maximum of 231 non-negative seconds (2,147,483,648 seconds or about 68 years). Which means that 32-bit UNIX systems won't be able to process time beyond 19 Jan 2038 at 3:14:07 AM GMT.
One of the common solutions will be to switch to 64-bit architecture systems that can store a maximium of 263 non-negative seconds (9,223,372,036,854,775,808 [9.2 Quintillion] seconds or about 292.27 Billion years), which is about 22 times the estimated age of our universe!
For the curious: A switch to 128-bit architecture systems would yield a maximum of 2127 non-negative seconds (170,141,183,460,469,231,731,687,303,715,884,105,728 [170 Undecillion] seconds), or about 18.4 Quintillion times as many as 64-bit systems.
* For informational purposes only
As of Sun Mar 10 23:25:27 GMT 2013 there are currently:
1,362,957,927 seconds since the UNIX epoch.
24 years, 10 months, and 8 days until 19 Jan 2038.
To give an indication if a Unix machine is 2038 Compliant, one can run this perl script to see if the time is incremented correctly.

I don't see why it matters. The big 2000 end of computers had no basis and so does this. Nothing bad happens even if the date flips. The 2000 thing had to do with BIOS dates yet they just start over. A BIOS update solves that with a new set of digits.
It should be less of a problem for an OS date system. They can simply code new date values, it all depends on when you start the date. So a year or 2 before the 'End-of-the-Date' apply the date patch.
We don't have to worry about the computers gaining conciseness until true quantum computing is realized which sounds like may not happen in Forahobbies and my life time... sorry kids, your future looks bleak! _________________________________________________________ 10% VIP Discount (Coupon Code: HQ-VIP-001 ) - Signup for web hosting at www.TweakedHosting.com/clients/aff.php?aff=004 and earn the HQ network of sites recurring income!

hahaha lol
That would sure be scary. I think there's a better chance of robots killing humans off as opposed to zombies... but zombies would be more fun and more of a fair fight. The robots could just keep making themselves more powerful, we would have to be hiding in caves all the time to survive like the Terminator movies. _________________________________________________________ 10% VIP Discount (Coupon Code: HQ-VIP-001 ) - Signup for web hosting at www.TweakedHosting.com/clients/aff.php?aff=004 and earn the HQ network of sites recurring income!
