The animal bodies are regulated by the 24h system.

No animal has any concept of what an hour is. If we humans decide to
divide the day into 173 in stead of 24, the animals wouldn't even
notice any difference.

Of course, the cows expect to be milked at the same time every day,
but they don't care if the farmer calls it 6 o'clock or 32.4 o'didly.
