 Test Case: Incorrect Date Display in RSS Block When Site Timezone is
 Changed

 Title: Verify if RSS block displays the correct date when the site
 timezone is changed from UTC+0 to UTC+9

 Test Type: Functional, Regression

 Environment:

     WordPress Version: 6.7.2
     Theme: Default
     Plugins: None (Test with a clean setup)
     PHP Version: 8.1
     Debug Mode: Enabled (define('WP_DEBUG', true); define('WP_DEBUG_LOG',
 true); define('WP_DEBUG_DISPLAY', false);)

 Preconditions:

     WordPress is installed and running.
     Site timezone is initially set to UTC+0 under Settings > General >
 Timezone.
     No caching plugin or custom time-related code is active.

 Test Steps:

     Navigate to Settings > General in the WordPress admin panel.
     Change the Timezone to UTC+9 (Tokyo, JST) and save changes.
     Create or edit an existing post and add an RSS Block.
     In the RSS Block settings, enter an RSS feed URL where pubDate is not
 in GMT/UTC.
         Example:
 https://www.mixonline.jp/DesktopModules/MixOnline_Rss/MixOnlinerss.aspx?rssmode=3
         This feed contains <pubDate> with a +0900 offset.
     Enable the Display Date option in the block settings.
     Publish the post and view it on the frontend.
     Observe the displayed date in both:
         Block Editor Preview
         Published Post View
     Compare the displayed date with the expected local time conversion
 based on the site’s timezone.

 Expected Result:

     The date should be correctly converted and displayed based on the
 site's timezone (UTC+9).
     Example: If the feed contains <pubDate>Wed, 13 Nov 2024 04:52:00
 +0900</pubDate>, it should display as November 13, 2024.

 Actual Result:

     [FAIL] The RSS block still shows the date in UTC instead of the site's
 local timezone.
         Example: It incorrectly displays November 12, 2024 instead of
 November 13, 2024.
     [PASS] If the date is correctly shown in the site's timezone.

 Post-Test Actions:

     Check the RSS Block source code for time conversion logic.
     Test with different timezones (e.g., UTC-5, UTC+5:30) to confirm if
 the issue is global.
     Report the bug to WordPress Core or Gutenberg development team if
 confirmed.
     Possible Workaround: Manually convert the time using a custom
 shortcode or plugin.

 Additional Notes:

     If using a caching plugin, clear cache and recheck.
     Try using different RSS feeds to see if the issue persists.
