Biological clocks, in the absence of environmental cues, tend to continue on a roughly 24-hour cycle, known as a circadian rhythm. This demonstrates the innate nature of these rhythms, which do not simply cease or become erratic without external time cues but rather maintain a cycle close to the 24-hour day.
