5. End of Unix Time (Numberphile, on youtube).
   

   Unix encodes time as a single signed integer number which increments every second. Unix time may be checked by typing date +%s.

   Time began for Unix 00:00:00 on 1/1/1970. This is the Unix Epoch.

   Why 00:00:00 1/1/1970 is the Unix Epoch.

   Time will end for Unix systems at 03:14:08  on 1/19/2038.

   The 32-bit version of the Unix time stamp will cease to work on this date, as it will overflow the largest value that can be held in a signed 32-bit number.
