Not quite as ridiculous as China’s One Time Zone.
"Currently, the time zone used within Xinjiang is roughly split along the ethnic divide, with most ethnic Han population in the area following Beijing Time, and most ethnic Uyghur population as well as population of some other ethnics in the area following Xinjiang Time."
I guess we see plenty of other units of measurement get tied up with identity (eg miles and ounces in the UK), shouldn't be surprising that it happens with time zones.
What would things be like if there were no synchronization or concept of hours, minutes, seconds at all?
There would still be loose concepts of time because of the position of the sun, but without precise time things might be less rushed.
In space we'll have to deal with a truly perpetual existence. I wonder what we'll be doing for scheduling 50,000 years from now.
Lots of train crashes.
No accurate ocean navigation.
And lots of other stuff would either not exist, or if it did, would kill/harm lots of people.
Also a fun fact, infrared light passes through the skull, deep into the brain and stimulates neurons. Sun's more than just UV!
