Elaboration:
Imagine Spacetime as a movie film reel. All of time (past, present, future) exist at the same time just like all the frames of that movie exist on that reel. If you want to time travel you go to the frame location on that reel. That location we call a WHEN but it is also a WHERE on the reel. Also, when physicists state that time and space are interwoven a film reel analogy encapsulates that theory well. So, time travel could be simply going to a specific coordinate in Space.
Theoretical Physicist Sean Caroll uses the film strip analogy in this video:

Disclaimer: Obviously, I have been watching too many Youtube videos and none of the concepts are my own. But I did think of the WHERE VS. WHEN regarding time travel analogy as I haven’t seen anyone state it that way yet.
Not in the same way, but UTC date and and time is a place and local time of day is a direction. Effectively, noon is when you face the sun as directly as you can that day, midnight is the opposite, 6am is looking straight into the future path of the Earth in orbit, 6pm is looking at the tail (tangentially since it’s a curve). That’s why meteor showers are best viewed around 3am: it’s a balance of looking into the Earth’s path but not losing visibility from sunlight. Day of the year is based on where midnight points, where the sun directly opposes (or, with a fair amount of astronomical data, what star the sun is aligned with; both are valid). What year it is can be determined by Sol’s position in our galaxy’s rotation. Change the scale (such as atomic clocks) and you lose that relation, but it can of course can be converted to earth time. Just a consideration if we ever actually become space-fairing. That introduces time dilation on a potentially noticeable scale though.
Time isn’t really determined by position, but rather our scale of time is based on astronomical position and vector.
