This page explains the timekeeping model and action economy that Trinity uses.

If you are familiar with standard d20, some of this page will make sense to you, but a lot of new concepts are presented here to expand the scope of timekeeping beyond combat.

Timekeeping and Action Economy

The notion of proper timekeeping being a necessary component of tabletop RPGs goes all the way back to Gygax. I find this ironic given that the early editions of D&D largely lacked a sensible timekeeping model and action economy, and the idea of tracking literal minutes in an adventuring day is cumbersome at best and absolutely insane at worst. That said, there is certainly merit to the idea, and - indeed - to accommodate more interesting mechanics that cover more territory than just combat, we need more means of tracking time that aren't annoying.

Combat Time

The smallest units of time we track is combat time, which is something of a misnomer because it also covers things like navigating cliffs or other exploration hazards. However, this part of the timekeeping system in Trinity is a legacy holdover from D&D, in which it was used exclusively for combat, so: there it is.

Combat time is tracked in rounds, units of time that cover 6 seconds. Each participant in the encounter (generally) has a turn in each round, in which they can take a number of actions. Some effects allow characters to have more than one turn, while other effects can cause a character to lose their turn.

Initiating Combat Time

When an encounter occurs, all participants roll initiative. This is d20 + your level bonus + the best of your Dexterity, Intelligence, and Bravery modifiers. Some effects may give you a bonus or penalty to this roll.

Once all participants have rolled initiative, play proceeds in order from highest to lowest initiative. Once the participant with the lowest initiative has taken their turn, the round ends and a new one begins, starting with the participant with the highest initiative.

Combat Action Economy

During your turn, there are three primary types of actions you can take: full, standard, and move.

On a normal turn, you gain one standard and one move action. You can combine one standard and one move into a full action. You can convert a standard into a move.

Exploration Time

One step above combat time is exploration time. This is an entirely novel concept to Trinity (and is partially imported from Journey, a game system we worked on for several years) and is not in any iteration of D&D, so this is where things start to get weird if you're used to that.

Exploration time is tracked in hands and watches. A hand is a unit of time that covers roughly 12 minutes, while a watch covers 20 hands, or 4 hours. So five hands equal an hour, and six watches equal a day.
