Note the correlation for x (tost time) and y (rbot time) is 0.923. The 0.000 is the P-value for testing (the true correlation is zero. It means there is no relation between x and y) versus (the true correlation is not zero. It means there is a relation between x and y). The formal test has the test statistics =7.5852 with n-2 degrees of freedom.

Q: For logistic regression in LDA, could we use autocorrelation function and variogram to explore the correlation structure of binary outcome variable? A: The answer is NO. “For binary or multinomial data, the marginal variance is a function of the mean, and hence the variogram of covariogram are not appropriate summaries of the dependence.”
