``strftime()`` and ``gmstrftime()`` format time and date according to locale settings. These functions are deprecated in PHP 8.1, and should be replaced with ``date()`` and ``gmdate()``, respectively, or with ``gmdate()`` or with ``IntlDateFormatter::format()``: both of them, with the right format.
