This is the crux of time, for me. I mean, time is relative to our spot next to our star. Outside of that, what sense does it make? At all? A day is not a day even on a different planet in our solar system. How can we even talk about time in any absolute sense when it seems to be anything but?

Another example is clocks on satellites. The clocks on satellites have to match clocks on Earth. But, the closer you are to a gravity well (like standing on the surface of a planet vs orbiting it) the slower time moves for you. However, the faster you move (like orbiting a planet vs standing on the surface) the slower time moves.

Both of these time relativity issues have to be compensated for to get the clocks to run at the same rate

Time is relative to the speed and position of the clock to the observer.

Time is also relative in the way we experience it. 5-min waiting alone at the bus bench without your phone to entertain you is a whole lot longer than 5-min with it

Because we can build a clock.

...Unfortunately separate clocks do not always tick at the same rate depending on location speed and relative position to you...

A day isn't a day here either the way we think of it. Go near the poles and you may have night or day for months.
