Its impossible to alter a table to add table.timestamps()

[rodriciru]

schema.alter( "Html", function( table ){
			table.addColumn( table.timestamps() );
		} );

->

Recieved a TableIndex instead of a Column when trying to create a Column.

Did you maybe try to add a column and a constraint in an ALTER clause at the same time? Split those up in to separate addColumn and addConstraint commands.
