Are you prepared for the Unix 2038 problem?
All 32-bit Unix/Linux-based systems store the system clock time internally as the number of seconds since the "Epoch." The latest time and date that can be represented as seconds-since-the-Epoch in that 32-bit signed integer is 3:14:07 UTC on Tuesday, January 19, 2038.

Bill Bradford explains some options for preventing this eventuality. Continue Reading
