Description

Java's Date class is horribly broken and should not be used. Unfortunately, we used it to return the results of the min/max for ColumnStatistics. That leads to lots of problems.

To fix this, we'll create new API methods that return it both as day of epoch and LocalDate. Both of them work much better.
