I like how there are at least three things that are immediately recognizable as wrong with this question.
Can time really exist if there was no frame of reference to measure it? We can only detect it by motion or entropy. It’s the only way of “time”. So if there was some point where there was nothing that moved, then time wouldn’t exist.
For that matter, there’s no way of measuring if time is even consistent. If it were constantly speeding way up, or slowing way down, we’d have no way of knowing.
Time is just a figment of our imagination so we can keep track of movement. Just like magenta isn’t a real color.
