Fun personal fact about me: I didn't learn to tell time until I was 9 years old. I was effectively blind until I was 8 when I first got glasses, so I had never actually seen a clock before then.

Don't get me wrong, I already had a concept of time, every time my parents or teachers would say the time numerically, but I simply never actually saw a clock in person until the year after I finally got glasses.

One day when I was 9, my parents left me home alone to briefly go to the local store. Still dumbfounded by my new glasses and how clearly I could see stuff, I started looking at stuff on the walls.

Then I saw the analog clock, just ticking away. I sat there for 5 minutes, just staring at it, counting every single tick of the second hand, and carefully paying attention to the slow movement of the minute hand.

Then I thought to myself 'Well shit, now I get it!'

I more or less figured it out all on my own. But if it was somehow a confusing universal time as OP suggests/asks about, I wouldn't have been able to figure it out on my own and would have still been really confused.
