Year 2038 Problem
The original Unix timestamp datatype (time_t) stores a date and time as a signed 32-bit integer representing the number of seconds since 1 January 1970. During and after 2038, this number will exceed 231 − 1, the largest number representable by a signed 32-bit integer, causing the Year 2038 problem (also known as the Unix Millennium bug, or Y2K38). To solve this problem, many systems and languages have switched to a 64-bit timestamp, or supplied alternatives which are 64-bit.
