One possible way to get started is to do what the ‘Distilling Free-Form Natural Laws from Experimental Data’ project did: feed measurements of time and other variables of interest into a computer program which uses a genetic algorithm to build functions that best represent one variable as a function of itself and the other variables. The Science article is paywalled but available elsewhere. (See also this bunch of presentation slides.)
They also have software for you to do this at home.
