01/01/1970 klokken 00:00:00 er 0 i unix tid. Derfor er det ofte at man ser den dato, når systemet ikke kan finde en gyldig dato.

 

Unix time (also known as POSIX time[citation needed] or UNIX Epoch time[1]) is a system for describing a point in time, defined as an approximation of the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970,[2]. Every day is treated as if it contains exactly 86400 seconds,[2] so leap seconds are not applied to seconds since the Epoch.[3] It is used widely in Unix-like and many other operating systems and file formats. However, Unix time is not a true representation of UTC, as leap seconds are not accounted for. A leap second in UTC shares the same Unix time as the second which came before it. Unix time may be checked on most Unix systems by typing date +%s on the command line.

On systems where the representation of Unix time is as a signed 32-bit number, the representation will end after the completion of 2,147,483,647 (231 - 1) seconds from 00:00:00 on 1 January 1970, which will happen at 3:14:08 on 19 January, 2038 UTC, although exactly how many seconds that is from now is not known because of unpredictable leap seconds. This is referred to as the "Year 2038 problem" where the 32-bit signed Unix time will overflow and will take the actual count to negative.
