According to a blog post on Read Write Web – this might be the worst case scenario in the year 2038. The internet might…… gulp…… die!
This is due to a bug, very similar to the Y2K Bug (millennium bug), recently discovered in the Unix operating system.
The bug, being dubbed the “2038 Bug,” arises because Unix-based systems store the time as a signed 32-bit integer, in seconds, from midnight on January 1 1970. And the latest time that can be represented in that format, by the Posix standard, is 3:14 AM on January 19, 2038. After that, times will wrap around and be represented as a negative number.
