In 2038 Computers Think It's 1901

On January 19, 2038 at 03:14:07 UTC, a signed 32-bit Unix clock hits 2,147,483,647 seconds after 1970. One second later, machines that still store time in four bytes wrap to December 13, 1901, 20:45:52 UTC. This is the Year 2038 problem, also called Y2K38. Not two-digit years. A 32-bit integer running out of room. 0:00 The last second 0:36 The Last Second 1:32 Two Billion Seconds 2:39 Why 1901 3:45 The Clock Already Broke 5:06 Four Bytes On Disk 6:09 And It Gets Worse 7:33 The Other 2038 9:00 What Does Not Happen 10:16 Who Fixes The Count Public-record dates and documented incidents only.
