Kernel Newbies y2038 project

Kernelnewbies is a community of aspiring Linux kernel developers who work to improve their Kernels and more experienced developers willing to share their knowledge.

The Kernel Newbies 2038 project:

All 32-bit kernels to date use a signed 32-bit time_t type, which can only represent time until January 2038. Since embedded systems running 32-bit Linux are going to survive beyond that date, we have to change all current uses, in a backwards compatible way.
