Unix 时间不确定性

Unix time uncertainty

我对Unix时间的理解有差距。 Unix 时间从 1/1/1970 开始计算,但在哪个时区? 假设是 1969 年 12 月 31 日 11p.m。在伦敦(-3600 Unix 时间) 在悉尼,他们有 8 个 a.m。 1970 年 1 月 1 日(28 800 Unix 时间)在同一时间。 所以我的问题是他们什么时候开始计算 Unix 时间的? 1/1 1970 是哪个时区?

谢谢

"Unix time" 应始终为 UTC。

维基百科在 https://en.wikipedia.org/wiki/Unix_time#UTC_basis:

上对此有一些进一步的措辞

The precise definition of Unix time as an encoding of UTC is only uncontroversial when applied to the present form of UTC. Fortunately, the fact that the Unix epoch predates the start of this form of UTC does not affect its use in this era: the number of days from 1 January 1970 (the Unix epoch) to 1 January 1972 (the start of UTC) is not in question, and the number of days is all that is significant to Unix time.
