The rest of the changes in the PR looks fine to me. Before reviewing the CSR, I think we should come to an agreement on the method naming.

I prefer `fromEpochMillis(...)` instead of the current `epochMillis(...)`. @RogerRiggs, @AlanBateman which one of these method names do you suggest we proceed with?
