Displaying DateTime in PXSelector

I would like to include the CreatedDateTime field in a PXSedlctor Dropdown, however I am having some challenges.

Initially I added some UI attributes to the standard CreatedDateTime field, this led to some confusing errors. So, I moved on to a non-priested read only field that would return the value of CreatedDateTime.

        [PXDateAndTime(DisplayMask = "G")]
        public virtual DateTime? OrderSetDateTime { get { return CreatedDateTime; } }
        public abstract class orderSetDateTime : PX.Data.BQL.BqlDateTime.Field<orderSetDateTime> { }

Using this method the date value shows but not the time. How would I show both in a single column?

Thanks
