Would the moon need time zones if people lived there? What time is it on the space station? Do they use GMT?

Since only one side of the moon is always facing the Sun, there would not be observed short-term positional change of the Sun at any fixed location. Hence a single time can be observed for the whole moon. This would have to be based on a reference point of time w.r.t. Earth.

The time on the space station is observed as GMT (Greenwich Mean time).

The moon has yet to be divided into time zones because nobody lives there and there isn't really a need to know what time it is on the moon. However, astronomers know that trying to describe events to other astronomers around the world would be very difficult if they had to use regular time from thier own time zone. Something that was supposed to happen at midnight in one part of the world would take place at noon in another part! For this reason, Astronomers use GMT, Greenwich mean time, or UTC, coordinated universal time. This is a 24 hour clock time that is the same for everybody, no matter where you are, so that midnight UTC is always Zero hours, regardless of whether the sun is directly overhead.

And by the way, the moon rotates almost exactly as fast as it orbits the earth, so the movement of the sun across the lunar sky would be pretty slow...

Day and night on the moon each last about two weeks. Combine them and you get what is called a synodical month.
The ISS is on Greenwich Mean Time.

If people start living there, time zones will be needed.

The same time it is here. Unless you from there.
It is read as GMT. Greenwitch Martian Time.
