  In a minimal flow, the hitting time is the exponent of the power law, as r
goes to zero, for the time needed by orbits to become r-dense. We show that on
the so-called Ornithorynque origami the hitting time of the flow in an
irrational slope equals the diophantine type of the slope. We give a general
criterion for such equality. In general, for genus at least two, hitting time
is strictly bigger than diophantine type.
