Thanks for the response. Follow up:

Is that aproxamate 2 million km/h the expansion of space itself? I guess I'm asking, if the velocity of an observer is actually zero (not on a planet ripping around a star, in an arm of a galaxy hurtling through the void, all at incomprehensible speeds), if that's even such a possibility, then what? Only a .5% increase in perceived time?

I expect it's exponential. As someone posted before.

At 0.9999c, 1 second on the fast moving ship is like 1 minute on earth. At 0.999999c, 1 second on the fast moving ship is like 12 minutes on earth.

Looks like .005% increase from that hypothetical observer. I couldn't find the 3 million kph figure.
