Or simply use an AbstractColumn for that, you can even create a reusable DateColumn:

public class DateColumn extends AbstractColumn {
   private String datePattern; //you can have a Pattern instead

//You can overload the constructor, to have default date patterns for example

   public DateColumn(IModel columnName, String datePattern) {
      super(columnName);
      this.datePattern = datePattern;
   }

public void populateItem(Item cellItem, String componentId, IModel model) {

      Document doc = (Document) model.getModelObject();
     SimpleDateFormat df = (SimpleDateFormat) DateFormat.getInstance();
      df.applyPattern(datePattern);

cellItem.add(new Label(componentId, df.format(doc.getDeliveryDate())));

   }
}

Then just use this class as you would with any other column, along with a pattern to apply to the format:

List<IColumn> columns = new ArrayList<IColumn>();

columns.add(new DateColumn(new Model("Delivery date"), "dd MMM yyyy '@' hh:mm a"));

The default java.util.Date converter within Wicket has varied between
releases.  I suggest adding this to the init method of your application
class and controlling the date format yourself if you need a specific
format:

        ((ConverterLocator) getConverterLocator()).set(Date.class, new
IConverter<Date>() {
            private static final long serialVersionUID = 1L;
            private final DateFormat mFormat = new
SimpleDateFormat("MM/dd/yy hh:mm:ss.SSS");
            public Date convertToObject(String value, Locale locale) {
                try {
                    return mFormat.parse(value);
                } catch (ParseException e) {
                    e.printStackTrace();
                }
                return null;
            }

            public String convertToString(Date value, Locale locale) {
                return mFormat.format(value);
            }

        });
