# Slot: time_unit 


_Unit of every time-valued number in this scope — the step size, any period, and the physical meaning of one model time-step. Declared at whichever scope owns the clock (network, integrator, observation); `tvbo.utils.units.time_unit_of` resolves a scope to its effective unit by walking outwards, and states the `ms` fallback once, at the end of that walk. Deliberately carries no default: a defaulted slot cannot be inherited through, so `ifabsent: ms` made an unset unit indistinguishable from one someone wrote, and masked an explicitly declared `s` one scope out. `time_scale` is accepted as a synonym._
