Y2K38 Watch Starts Saturday
Jon Masters writes "I just wanted to remind everyone that Saturday, January 19th 2008 will mark the beginning of the 30-year countdown to the Y2K38 bug, when Unix time will overflow 32 bits. Some 30-year loan calculation software might start having problems with this over the weekend."
Put simply, a lot of software is poorly written and uses int as synonymous with time_t (or somesuch). The two are often interchanged by programmers; particularly those with a Windows background who can't find CTime (or whatever it's called) on non-Windows platforms.
;)
Moving to 64-bit machines won't fix all the magic 32-bit binaries out there but software that's recompiled for 64-bit machines will automagically use 64-bit ints where the programmer held the time in an int.
Of course, I've seen a lot dumber bugs than ignoring to use the operating system's time structures and methods for dealing with time so I don't doubt that there are some bugs that actually will need some serious considerations made.
I guess it's a fault of the Unix people from way back. They made this epoch thing and used a 32-bit number to store the number of seconds since it. I guess they were assuming that all their software would have been replaced by something better on bigger machines. They shouldn't have written such reliable software and then maybe some of it would have been replaced by now
I drink to make other people interesting!
