Slows station time to 2x real time, instead of 12x (#4319)

## About The Pull Request
This PR makes it so the displayed station time in-world moves more
slowly, at a rate of 2x normal time. It has no effect on the speed of
the game itself, only the time displayed on clocks.

Mostly for lore reasons, so players aren't playing a 36-hour shift in
setting every time they play the game. Just something minor that always
bothered me.

This does mean Night Shifts are longer, though.

Includes upstream TG PRs 92428 and 92469.

## Why It's Good For The Game
Makes time more accessible for players by slowing it down. Now you can
set meetings for specific times in-game and have a rough idea of when
that will be!

## Proof Of Testing
Should just work out of the box. Compiles with no errors.
