Loved the article! There are so many great details such as the standardization of UTC happening after UNIX time invented, UNIX itself being born before the epoch, and all the great insight into the morass of 64 bit time across modern OSes.

Putting on my pedantic hat though, I see that East and West were switched in the discussion of Japan's unique 50/60Hz AC frequency split, and I can't get my mind off it. Hope you can make the edit.
