Time is one thing happening after another, the same point in time is the point in that sequence. If two things are happening at once, it’s the same time, even if it’s dark where one thing is happening and light where the other is.
People use days as a measure of time because days take place on a consistent cycle, thus taking the same time, but that doesn’t mean the light or relative position to the sun is time itself. Same with clocks. It’s also the same with those weights we use to keep track of grams and pounds and such–they’re markers of what we chose to label as grams or pounds, but I think it’s stupid that their current condition or decomposition fundamentally changes what a pound or a gram is.
I have yet to see any argument for the non-existence/objectivity of time that hasn’t depended upon the speaker’s own lack of comprehension that what they are perceiving as time is merely a spatial thing that we happen to use to measure it. A tape measure isn’t space, so stop talking about the sunlight or a clock like they are one with time.
