* e_cell_date_new:

*
* Creates a new ECell renderer that can be used to render dates that
* that come from the model. The value returned from the model is
* interpreted as being a time_t.
*
* The ECellDate object support a large set of properties that can be
* configured through the Gtk argument system and allows the user to have
* a finer control of the way the string is displayed. The arguments supported
* allow the control of strikeout, bold, color and a date filter.
*
* The arguments "strikeout_column", "underline_column", "bold_column"
* and "color_column" set and return an integer that points to a
* column in the model that controls these settings. So controlling
* the way things are rendered is achieved by having special columns
* in the model that will be used to flag whether the date should be
* rendered with strikeout, underline, or bolded. In the case of the
* "color_column" argument, the column in the model is expected to
* have a string that can be parsed by gdk_color_parse().
*
* Returns: an ECell object that can be used to render dates.
