This is "time dilation", which has been well documented in relativity studies.

Everyone who's ever flown in an airplane has aged however imperceptably more slowly from being that much further from the local gravitational source, i.e., the earth.

I suspect though that "changing" time would require a corresponding change in the entropy of the entire universe, since that is what most likely sets the "arrow of time".

I'm intrigued by your post. I think I'll write the government and see if I can get a grant to study stewardesses.

Yup, that's right. These experiments have been done before with airplanes, but the shifts forward were extremely tiny. The were only measurable with cesium clocks, down to billionths of a second, I think.
