First, people look really hard to discern whether or not the constants are constant. So far, they are. See [1-3] for quick examples.
Second, if the constants were changing, we could simply reference to the value of the constant on a certain date. As the rate of change is now guaranteed by existing experiments to be small, any shift would be very tiny, and easily calculable.
The question of the constancy of constants remains a very good one. That question is, by its very nature, its own constant of science.
