[php-src] Issue #18937: Files tar extracted from Phar have Jan 1 1970 as date

Issue: https://github.com/php/php-src/issues/18937 Author: emteknetnz ### Description The following code: ```php <?php // run.php // run touch myfile in terminal first $phar = new PharData('archive.tar'); $phar->addFile('myfile'); // Adding explict options makes no difference // $phar = new PharData( // $filename, // FilesystemIterator::SKIP_DOTS|FilesystemIterator::UNIX_PATHS, // null, // Phar::TAR // ); // Name file a.tar.gz if using this option, tar -xzf has the same date issue // $phar->compress(Phar::GZ); // Note that buildFromDirectory() seems to have the same issue: // $phar->buildFromDirectory() // // Also note that extractTo() work as expected i.e. has today date // $phar->extractTo('. 'myfile'); ``` ```bash touch myfile ls -al | grep myfile php run.php tar -xf archive.tar ls -al | grep myfile ``` Resulted in this output: ``` -rw-rw-r-- 1 myuser mygrp 0 Jun 25 19:33 myfile -rw-rw-r-- 1 myuser mygrp 0 Jan 1 1970 myfile ``` But I expected this output instead: ``` -rw-rw-r-- 1 myuser mygrp 0 Jun 25 19:33 myfile -rw-rw-r-- 1 myuser mygrp 0 Jun 25 19:33 myfile ``` ### PHP Version ```plain # DOES NOT AS EXPECTED: PHP 8.4.8 (cli) (built: Jun 9 2025 13:50:18) (NTS) Copyright (c) The PHP Group Zend Engine v4.4.8, Copyright (c) Zend Technologies with Zend OPcache v8.4.8, Copyright (c), by Zend Technologies PHP 8.3.22 (cli) (built: Jun 9 2025 14:03:36) (NTS) Copyright (c) The PHP Group Zend Engine v4.3.22, Copyright (c) Zend Technologies with Zend OPcache v8.3.22, Copyright (c), by Zend Technologies PHP 8.2.28 (cli) (built: Mar 13 2025 18:13:49) (NTS) Copyright (c) The PHP Group Zend Engine v4.2.28, Copyright (c) Zend Technologies with Zend OPcache v8.2.28, Copyright (c), by Zend Technologies # WORKS AS EXPECTED: PHP 8.1.32 (cli) (built: Mar 13 2025 18:27:44) (NTS) Copyright (c) The PHP Group Zend Engine v4.1.32, Copyright (c) Zend Technologies with Zend OPcache v8.1.32, Copyright (c), by Zend Technologies ``` ### Operating System Ubuntu 24.04
