"Begin Light" at 1:42 am? – Entrain Review

If this is what it takes to "entrain" my body to a new time zone, count me out. In order to reduce my adjustment time from 9 days to 4 days, the app said I should commence a light-dark schedule of "beginning light" in the wee hours of the morning in the days before my trip, and "beginning dark" in the early afternoon. Does anyone actually do this? Do they want me to set an alarm at 2 am, wake up, turn on a light, and fall back asleep? One of the strangest apps I've ever seen.
