Time
Your GM may use different timescales depending on the situation. They may use minutes when exploring buildings and other artificial spaces, hours when tracking over outdoor locations or structures whose size is so vast that the characters are effectively outdoors. For longer journeys, particularly interstellar travel, days are used.
During any contest, the pacing is more frenetic, and we use a standard of units, which are covered in the headings below:
free-action (f-act)
bonus-action (b-act)
re-action (re-act)
move-action (mv-act)
The move-action is considered to occur at the same time as any other actions in a contest (except another move-action). This means that it occur's over the six-second time period of the round.
you can move up to your speed. You can move at any time, either before or after your act. You can also split your move, carrying out part of your movement before your act, and part after your act.
main-action (m-act)
round (rnd)
A round is a unit of time usually within the context of a contest, and is roughly 6 seconds duration. During the round, each creature participating in a contest takes a turn.
minute (min)
scene
A scene is around 10 minutes of time.
