----------------------------------------------------------------

[~Leonard Xu] this is not entirely correct, it can still show false positives 
because only an optimizer run can figure out whether a attribute looses its 
properties. I would keep this issue for now.

> A call to `Table.getSchema` can result in false positives with respect to 
> time attributes. Time attributes are converted during optimization phase. It 
> would be helpful if we could execute parts of the optimization phase when 
> calling this method in order to get useful/correct information.
