Clock Variables

Clock variables are timer identifiers used in transitions to measure elapsed time and enforce time-based conditions.

To view and manage clock variables, click the clock icon in the left sidebar. The panel shows all clocks defined for the currently active automaton.

Adding a clock

Click + or the add button to create a new clock. A clock has a single required field: its name. This name is used in clock constraints and clock resets on transitions.

Unlike global state variables, clocks have no type or default value — they are purely time counters.

Deleting a clock

Click the trash icon on a clock card to remove it. Before deleting a clock, make sure no transitions in the automaton reference it in a clock constraint or clock reset.

Using clocks in transitions

Once a clock is defined, it becomes available in the Clocks section of the transition configuration panel:

Clock Constraint — add a condition such as clk_retry >= 5 min that must be satisfied for the transition to fire
Clock Reset Variables — select clocks to reset when the transition fires
