What’s the Unix Epochalypse?

The Unix Epochalypse (or the Year 2038 problem) is the day clocks on a number of systems will flip from to . This is because of the use of a 32-bit signed integer for the current seconds since midnight UTC on , the Unix epoch. Values only from -2,147,483,648 to 2,147,483,647 are stored. When finally reaching the limit, it’ll be the seconds before the epoch starting at the lowest supported integer.

If you have yet to make the complete shift to 64-bit, expect some strange things to happen later. The age of 32-bit is over. The time of 64-bit has come!
