Most will, I now expect few Y2.038K problems.

I have some code on my website that stores times as decimal numerals. 
Until 2038, a 64-bit time_t stores exactly the same thing as a 32-bit 
time_t. There was no problem converting THAT to 64-bit. The only thing 
that changed was code to handle dates outside of the 32-bit range (which 
had been stored as julian dates).
 
Since I want to see what my computer does with the leap second, so I 
have written this short PHP script (runs standalone, not as a webpage) 
that prints the GMT time every second until 10 seconds into the new year.

If you want to use it, you have less than 4 hours to get it going. It 
stops just after midnight so you can see the important part.
