In arguing for an advantage of Standard over Daylight time the authors naively ignore that clock time is just a coordinate with arbitrary origin. In Matthew 20:1-16 KJV:

it appears that at the time of writing time was reckoned six hours behind the current convention: the first hour was around sunrise, people began work then; the eleventh hour around sunset, people ended work then.
This system is still widely in use in Ethiopia (and reportedly in other parts of east Africa though I have no direct experience). If you have a meeting at "three o'clock" you should turn up at 10:00. The meeting will probably start at 10:30 ... possibly because you have to call at least one other person who thought the meeting was at 15:00. ;-)
I believe there's a link to an article about this phenomenon in tz-links.html.
The harmful effects arise from the twice-yearly adjustment, not the absolute setting.
On a slightly related note, I wonder how those of us who were accustomed to regular large adjustments (e.g. 15 hours after crossing the Pacific Ocean) will cope when we resume our itinerant lifestyles when the current plague gets more under control? Will our bodies remember conquering jetlag, or will the first couple of trips be accompanied by sleepless nights and zombie days?

I think what you described about the clock system in East Africa is a problem with naming of hours instead of actual time differences. It is just like how English call a month Octo-ber despite it's now generally accepted to be the tenth month of a year. Another thing of note is that 15-10 is not 6
