Change Date-Time to Date only
I am working with data with date and time format. But then, I need to group the data by date regardless the time. But because the time is there, I can't use aggregate for that (or did I miss something?)
I notice that I can change the attribute type to date only, if I re-import the data from the original excel file. But I already process the data. It's kind of troublesome to redo all the process again starting from importing. Well, I notice that I can export then import again to change the date format.
But.. can I just change date format inside the rapidminer?
