Convert datetime to date in calculated field

Hi,

How to convert a date time field to date format only in calculated field of data entity ?

I want to add new field for my data entity. It is a date from CreatedDateTime field, but I don;t need the time, only the date.

After create the View method and then add it to a new field of my data entity, with  DateUnmappedField, I've put the EDT in the field property to TransDate, but the result still with the time. Guess I need to convert it first in my View, but I don;t know how.

Thanks,
