Wrong. A standard demonstration in GR textbooks is to show that in the
slow-motion weak field limit, the spatial components of the equation
of geodesic drop out. In other words, in the "Newtonian limit",
gravitation is completely accounted for by the *curvature of time*.
At high speeds and/or in strong fields, the spatial components of
the equation (i.e. curvature of space) become significant, accounting
for the doubling of the gravitational deflection of light over the
Newtonian calculation.
Currently I working through D'Inverno and Vickers for the second
time, so I am certainly no expert on this. But you can find a
derivation in section 10.6, "The Newtonian Correspondence".
