Correct. However, the die was cast on this in 1958 when the second was defined in terms of atomic behavior.

It was 1967.

At that point, the game was up, since the basic unit of time was decoupled from the day. We transitioned from having rubber seconds, to having rubber days. I suppose we could push this back further when the second was defined in terms of the mean solar day in 1900

...which happened in 1956 (ratified in 1960).
