Extracted from article:
Unix time is currently defined as the number of seconds which have passed since 00:00:00 UTC on Thursday, 1 January 1970, which is referred to as the Unix epoch. Unix time is typically encoded as a signed integer.[1]
[1] refers to "single-unix-spec-4.16"
↑↑ could someone refine here above and here below statement? ref. [1] - does not stipulate that Unix time is typically encoded as a signed integer. Instead it emphasizes: If the year is <1970 or the value is negative, the relationship is undefined. ... ↓↓ |
The Unix time 0 is exactly midnight UTC on 1 January 1970, with Unix time incrementing by 1 for every non-leap second after this.

- The Single UNIX Specifcation does not, as far as I can tell, require that the time be epresented as a signed integer, but it does allow it and, in practice, most if not all UN*Xes have
time_tas a signed type. I've moved the reference after the first of the sentences you quoted, so it only applies to the definition of Unix time, not to the claim that it's typically encoded as a signed integer. Guy Harris (talk) 23:09, 30 August 2023 (UTC)
