Not just you, your dog, the cat, the fly on the wall.
Studying that clock seems to have a lot to do with jet-lag:

Seem obvious; I sleep, I wake up...repeat; but figuring it all out was worth a Noble Prize:

I agree all points on your article. I would like yo share some points here. The time machine work is normally credited with the popularization of the concept of time travel by the use of a vehicle that permits an operator to travel purposely and selectively forwards or backwards in time.

A day or sol on Mars is 24.6 hours long. NASA teams that worked with Pathfinder and Sojourner had to struggle with the probes' martian schedule. Perhaps future colonists may benefit from a drug that easily adapts their circadian rhythm to this. They won't have much room for error at base camp "Mark Watney". ;)
