Abstract
The `frozen' character of general relativity (and background independent theories) is usually considered to be a problem for the theory. However, the most obvious resolution of this problem, involving correlations between dynamical variables, can be shown to provide a natural explanation of the appearance of time in timeless mathematical structures. I argue that this response can resolve a problem with Tegmark's extreme structuralist position, namely how to account for the appearance of time and change given that the structures in question are taken to be mathematical and, therefore, timeless.
