 /**
- *  smarty_function_bit_select_datetime
- *
- *	NOTE: This code looks good but needs intensive testing, especially with different date/time formats.
- *
- *	This function generates HTML code that adds a date picker to an HTML form.
- *	Depending on Bitweaver settings (Administration/Themes/Theme Settings)
- *	this can be the ordinary Smarty way of date/time picking (see html_select_date and html_select_time functions)
- *	or a nice javascript calendar.
+ * smarty_function_bit_select_datetime
  *
- *	Parameters:
- *	name	The name of the inputfield. Use this to identify the date/datetime input from other inputs. (will be used for <input name="..., defaults to 'date'.
- *	showtime	defines whether you need a date or datetime picking method. Set to 'true' or 'false', defaults to 'true'.
- *	format	The datetime format used to display/return the timestamp. Defaults to the user's preference on this Bitweaver system.
- *	time	The time value to be displayed, in the format given in the format parameter. Defaults to the current system time.
+ * Generates an HTML5 date/datetime-local input for form date picking.
  *
- *	Usage sample:
- *	<form action="edit.php" method="POST">
- *		{formlabel label="Test JSCalendar"}
- *		{forminput}
- *			{bit_select_datetime name="mydate2" time=$gContent->mInfo.start}
- *		{/forminput}
- *	</form>
- *
- *	Later, in edit.php, use this code to obtain the timestamp in UTC:
- *	$timestamp = $gBitSystem->mServerTimestamp->getUTCFromDisplayDate(_REQUEST['mydate2'])
+ * Parameters:
+ *   name      Field name. Defaults to 'date'. A hidden field with this name carries the Unix timestamp.
+ *   showtime  Show time selector. 'true' (default) or 'false'.
+ *   time      Unix timestamp to display. Defaults to now.
  *
+ * Server usage: $_REQUEST[$name] contains a Unix timestamp.
