We use the following class for date columns:

import java.util.Date;
public class DateTimeColumn<T> extends PropertyColumn<T>
{

public DateTimeColumn(IModel<String> displayModel, String
propertyExpression, String format)
{

}
public DateTimeColumn(IModel iModel, String sortProperty, String
propertyExpression, String format)
{
super(iModel, sortProperty, propertyExpression);
this.format = format;
}
//**********************************************************************************************************************

private class DateTimeModel implements IModel<String>
{
private final IModel inner;
private static final long serialVersionUID = 190887916985140272L;
private DateTimeModel(IModel inner)
{
this.inner = inner;
}
public void detach()
{

}
public String getObject()
{
