 Displaying the Value
-====================
+********************
 
 Since the Time class extends DateTime, you get all of the output methods that provides, including the format() method.
 However, the DateTime methods do not provide a localized result. The Time class does provide a number of helper methods
 to display localized versions of the value, though.
 
 toLocalizedString()

+===================
 
 This is the localized version of DateTime's ``format()`` method. Instead of using the values you might be familiar with, though,
 you must use values acceptable to the `IntlDateFormatter <https://www.php.net/manual/en/class.intldateformatter.php>`__ class.
