Questions tagged [year2038]

The "Year 2038 problem", a.k.a. Unix Millennium Bug, affects systems that use a signed 32-bit integer for the number of seconds since the "unix epoch" or 00:00:00 January 1, 1970. For such systems, the maximum date they are capable of expressing is 03:14:07 January 19, 2038.

Many "unix-like" systems express the current system time as the number of seconds since 00:00:00 January 1, 1970. For systems that use a signed 32-bit integer, which has a maximum possible value of 2,147,485,547, the maximum possible date is then 03:14:07 January 19, 2038, at which time adding one second will cause an integer overflow and result in a negative number, which will correspond to a time in the year 1901.

This Wikipedia article describes it in full.

How to choose MySQL column data types resilient to year 2038 -rollover?

January 19, 2038 03:14:07 GMT is now less than 20 years away. That's the time that UNIX's 32-bit timestamp rolls over. I'm working on designing some MySQL tables that may still be in use at that time. This is the so-called Year 2038 problem. It…

Is there a y2k12 issue analogous to y2k?

This is a bit of a whimsical question inspired in part by the publicity for the movie 2012 but it is one that could have real implications for software systems. (If not in 2012, then definitely in 2038.) There are all sorts of doomsday predictions…
