If we were to live on other planets, would we also have daylight savings time?

that depends on their axial tilt, if they have one, and how its alignment relative to the host star changes, or not, throughout the year.
Mars for example, has a similar tilt to Earth, and thus has seasons. Therefore Martians could have daylight savings time, if they so choose.

They’d probably be practical and set their clocks to show noon when the Sun is the max height.

Only if there were farmers.

I forgot that is why it started^
