The time system was one of the real interesting things from the documentary to me. This Seiko page explains the time system well: https://museum.seiko.co.jp/en/knowledge/wadokei/huteijihou/

12 hour day (what is 24 hours in modern time). Daytime is always 6 hours and night time is always 6 hours. The absolute length of the hours changes with the seasons.

There's an android app for it even: https://f-droid.org/en/packages/com.aragaer.jtt/

I just started using it recently and I really like it. My mood is very much affected by exposure to daylight and it really helps to plan my day around the sun, rather than arbitrary numbers on a clock.
