I am able to change Catalog Price Rules'
to_date from "date" datatype into "datetime", by overriding the classes:
and changing the datatype of the table columns
catalogrule.to_date into "datetime".
Is doing the latter safe? Or should I somehow create or modify some files, maybe in an
sql folder somewhere, e.g. my module's? Or could anyone point me to some resources I can peruse to achieve such? I just want to do this properly.
