Unix time is the humber of seconds since 1970. Seconds are a physical thing. Unix time references the number of "cycles of the radiation produced by the transition between two levels of the cesium 133 atom" UTC measures time. This article is silly.
- masklinn 7y ago> Unix time is the humber of seconds since 1970. It's not, and it has never been. The original unix time was "the time since 00:00:00, 1 January 1971, measured in sixtieths of a second", this got modified multiple times until it settled upon the number of UTC seconds since 1970-01-01T00:00:00Z, meaning it's non-monotonic, non-continuous, and not based on "physical" seconds.
