Notion of wall clock time is probably unnatural and harmful. Humans for millenia did not follow wall clock time to wake up, go to bed, go to work etc. they rather followed the sun. Following the sun is natural because we all need light. For better mood, for being able to do work outside or for vit d. We should rather sync up our schedules with the sun rise/sun set (while minimizing the total wall-clock delta and confusion people experience).
