[MAINTENANCE] Replace strftime in CalendarController
The function strftime "has been DEPRECATED as of PHP 8.1.0. Relying on this function is highly discouraged." See the official documentation for details.
The calendar view currently fails with a runtime "Oops" because of its use of strftime when the default debug settings are enabled in the TYPO3 backend. This setting in config/system/additional.php can be used to work around this problem:
$GLOBALS['TYPO3_CONF_VARS']['SYS']['exceptionalErrors'] = 2048;
I wonder whether the formatting of the year with two digits like in $title = strftime('%x', strtotime($title)); is reasonable for historic books and journals which typically are older than our current century and which sometimes cover more than a single century.
