I've tried thinking more of time as a fourth dimension rather than a simple parameter. That has helped a bit.
I'm wondering if time is defined in terms of the rate of change of distance with respect to speed; rather than the more usual formulation. Does that make any sense.... or help?
Here's something that should amuse you: in particle physics and gravitation, one usually defines the speed of light as c=1. This means that time is defined as the distance in the fourth dimension which is measured in the same units as distance in space. It's like using (light)years as a distance measure.
