I also noticed a funny thing browsing the year 2038 website : 
http://www.2038bug.com/demo.html shows the first negative date given by a negative int32
number.

Again, since Ged wasn't clear: This is NT. NT does not use Unix time.

Then what DOES NT use to calculate time?

Win32 uses SYSTEMTIME and FILETIME structures to store and calculate
the time/date which if I recall correctly user a large int to store
and calculate time since 1970. No problem with space there. See

http://msdn.microsoft.com/en-us/library/ms725473(VS.85).aspx

I am curious if the posix subsystem has any problems with the 2038
bug. Most likely not as it should use the correct native functions
internally. Any POSIX application that expects normal 32bit time_t
under Services for Unix or Subsystem of Unix applications would still
be affected. Again, your talking about 1/2 of .0001% of all
applications running on Windows though. Maybe a few other applications
that have been ported over using a third party static libc doing its
own timekeeping would also be affected but like Alex and Ged have
pointed out, its a Unix problem. Yes they do exist, Unix, Linux and
friends are not perfect.

I wonder what Apple's 2038 plans are. Most likely to kill support for
32bit long before ;)

Just to make the point clear: It will overflow on January 1st, 584942.

Well, Windows and ReactOS ARE using unix time. Not in the kernel, but in
the crt.
And actually this IS an issue on reactos at this time.

Windows has solved the issue, by adding 64 bit time_t support, which is
used by default and can only be overridden with defining
USE_32BIT_TIME_T when compiling your software.
Our crt headers currently still contain a hack that defines this by
default, because we don't have any 64bit time_t support in out crt, at
least not in trunk.
I recently added a new time implementation to the amd64 branch that
supports 64 bit time_t. It should work, but it's not fully tested.

Regards,
Timo
