The animal bodies are regulated by the 24h system.

Not sure what you are talking about. Animal rhythms are related to a daily
cycle, it has nothing to do with "hours".

Further to this, Circadian Rhythm is very approximate, that is, it adjusts with the seasons, day/night length, temperature, in some cases the phases of the moon, and more. Try setting train schedules from a process that may alter by tens of minutes on any given day.
