-This function generates the column headings for the chart.

+To retrieve values from it, use &get_date_from_form().
+
+Inputs
=over 4
-Inputs: $CacheData, $studentInformation, $headings, $spacePadding
+=item $dname
+
+The name to prepend to the form elements.
+The form elements defined will be dname_year, dname_month, dname_day,
+dname_hour, dname_min, and dname_sec.
-$CacheData: pointer to a hash tied to the cached data database
+=item $currentvalue
-$studentInformation: a pointer to an array containing the names of the data
-held in a column and is used as part of a key into $CacheData
+The current setting for this time parameter. A unix format time
+(time in seconds since the beginning of Jan 1st, 1970, GMT.
+An undefined value is taken to indicate the value is the current time.
+Also, to be explicit, a value of 'now' also indicates the current time.
-$headings: The names of the headings for the student information
+=item $special
-$spacePadding: The spaces to go between columns
+Additional html/javascript to be associated with each element in
+the date_setter. See lonparmset for example usage.
-Output: $Str
+=item $includeempty
-$Str: A formatted string of the table column headings.
+=item $state
+
+Specifies the initial state of the form elements. Either 'disabled' or empty.
+Defaults to empty, which indiciates the form elements are not disabled.
=back
+Bugs
+
+The method used to restrict user input will fail in the year 2400.

+# Nested table routines.
+#
+# Routines to display form items in a multi-row table with 2 columns.
+# Uses nested tables to divide form elements into segments.
+# For examples of use see loncom/interface/lonnotify.pm
+#
+# Can be used in following order: ...
+# &start_pick_box()
+# row1
+# row2
+# row3 ... etc.
+# &submit_row()
+# &end_pick_box()
+#
+# where row1, row 2 etc. are chosen from &role_select_row,&course_select_row,
+# &status_select_row and &email_default_row
+#
+# Can also be used in following order:
+#
+# &start_pick_box()
+# &row_title()
+# &row_closure()
+# &row_title()
+# &row_closure() ... etc.
+# &submit_row()
+# &end_pick_box()
+#
+# In general a &submit_row() call should proceed the call to &end_pick_box(),
+# as this routine adds a button for form submission.
+# &submit_row() does not require a &row_closure after it.
+#
+# &start_pick_box() creates a bounding table with 1-pixel wide black border.
+# rows should be placed between calls to &start_pick_box() and &end_pick_box.
+#
+# &row_title() adds a title in the left column for each segment.
+# &row_closure() closes a row with a 1-pixel wide black line.
+#
+# &role_select_row() provides a select box from which to choose 1 or more roles
+# &course_select_row provides ways of picking groups of courses
+# radio buttons: all, by category or by picking from a course picker pop-up
+# note: by category option is only displayed if a domain has implemented
+# selection by year, semester, department, number etc.
+#
+# &status_select_row() provides a select box from which to choose 1 or more
+# access types (current access, prior access, and future access)
+#
+# &email_default_row() provides text boxes for default e-mail suffixes for
+# different authentication types in a domain.
+#
+# &row_title() and &row_closure() are called internally by the &*_select_row
+# routines, but can also be called directly to start and end rows which have
+# needs that are not accommodated by the *_select_row() routines.
