So I understand that there are time zones and the time at any given moment varies across locations, BUT is there a more subtle difference from place to place? For example, does southern California and northern California have like a time difference of a couple seconds or something like that? Is every location, no matter how far from each other, slightly different? Because, for me, it doesn’t make sense that there is just some line that you cross and all of a sudden you’re 1 hour ahead or 2 hours ahead etc.

When you are on the phone with someone, are you talking to them at the same time or at different times? 5 minutes is always 5 minutes no matter where you are. Time zones are set by humans to match daylight hours with time in the day- more or less so noon is when the sun is directly overhead. We have to maintain consistently so we can’t say it’s 12 here and next door it’s 12:01, no one would know what time it is. We group them into zones into where it makes the most sense. It literally is an imaginary line where you have to set the clock forward, so you can match everyone else in the area.

Timezones are used to track keep places/people aware of the same time for societal reason. They are split about roughly around how much daylight there is.

Each location has its own local time. This didn’t matter for most of history.
Once we had trains there was a need to ensure that clocks were synchronised to ensure that trains departed at the same time for everyone concerned. These times meant there was a need to have standardised time over a large area.
WWI in Germany saw the need to make maximum use of available daylight in factories and this practice of *daylight saving* was quickly adopted in high latitude locations. In equatorial locations there is no point in *daylight saving* as sunrise and sunset don’t vary much throughout the year.
Tracking time is entirely a human construct
There’s no reason we can use a Universal clock for the whole planet. Technically we have that UTC or Universal Time, also called Greenwich Mean Time or GMT.
The problem is that people base their day on the time. Noon is when the sun is the highest, you go to work for 8am, etc
If you use Universal time noon would be in the evening in North America and people don’t like that. Which is why timezones exist.
Timezones are kinda, not really, but mostly just lines drawn on a map that says “for this area the clock will be X hours ahead or behind GMT so that noon is when the sun is directly overhead”
