 | | The UNIX operating system keeps track of the current date and time by maintaining the number of seconds that have elapsed since Thursday, January 1, 1970 at 00:00:00 UTC (Coordinated Universal Time, also called Greenwich Mean Time or Zulu Time). This number is stored in a signed long integer, which means that, assuming a 32-bit system, UNIX timekeeping will break on Tuesday, January 19, 2038 at 03:14:08 UTC when the value overflows and becomes negative. | |
