I just realized that there are people who time travel every day. What about people who live on the western boundary of a time zone, and work in the next time zone? For example, I live in the Eastern time zone, and work in the Central time zone.

If you move, you have time travelled into the Earth’s future! It doesn’t matter how. Walk across your kitchen, and you have time-travelled into the Earth’s future. Unfortunately, no clock yet made could pick that up.
But if you move fast enough for long enough, an atomic clock would pick it up. Weird stuff, I know.
