This is just one piece of the puzzle, the findings for the mortality actually weren't as robust as I would have hoped. ... I think they would have had stronger results if, instead of just looking at chronotype, they had looked at chronotype alignment: So, are people going to bed at their correct time?

It's interesting, and it would definitely take some follow-up to see what that means. Is that depression? Is that anxiety? Are there specific psychological phenomena that are more or less related to chronotype, especially the disparity between your chronotype preferred timing and the actual timing of sleep?

The circadian clock is the central conductor of the many clocks that are found in nearly all tissues of your body, this clock remains synchronized with the external day through regular exposure to light.

However, the treatments that are developed for jet lag can be used for less prevalent, though far more significant societal problems including delayed sleep in teens( in whom we have an ongoing clinical trial using the flash technique) and shift workers who try to flip between a night time schedule for work and a day time schedule for leisure.

In essence, using the night before you traveled from California to New York would move your circadian system two-thirds of the way there before you even left.

This is one of the real advantages of this system - you can change circadian timing while you sleep, without interfering with sleep.
