Gravitational time dilation explanation for Newtonian gravity?

I seem to recall reading a post a long time ago (that I cannot find) that gravity in the Newtonian limit (eg the Solar system) can be completely explained in terms of gravitational time dilation alone.

In his book, Gravity from the Ground up, Schutz argue that All of Newtonian gravitation is simply the curvature of time. Can anyone shed light on this since I don't understand his argument at all?

Try Lecture 5 by Bertschinger:

He takes the Newtonian limit at 1:03:00.

The "stretched" time dimension causes both: gravitational time dilation and Newtonian gravitation. You have to visualize it to understand it:

That diagram is wrong. It shows the ceiling clock runs slower than the floor clock
No it doesn't. The ceiling clock gets ahead of the floor clock in proper time, so it runs faster.
 
Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. The Relativator was sold by (as printed) Atomic Laboratories, Inc. 3086 Claremont Ave, Berkeley 5, California , which seems to be a division of Cenco Instruments (Central Scientific Company)...
