Fair enough.

How about: On any continent rotating clockwise, walk 1 mile South. Wait until the continent rotates 30°. Walk 1 mile East. Wait until the continent rotates 30°. Walk 1 mile North.

For counter-clockwise rotating continents, change 30° to 210°.

Note: You may like to start waking sightly before 30° (210°) rotation has occurred so that the rotation during the walking time is also accounted for.
