The experiment was conducted over 49 days, and as a result, the group who drank caffeine said the biological clock was delayed about 40 minutes (it shifted behind). By the way, the biological clock of the person who took the light shifted by a factor of 80, and a person who received both caffeine and light 105 minutes shifted.
