Comment:

 == Test Report
 === Description
 🟠 This report validates that the indicated patch works as expected with
 some caveats regarding Unit Testing.

 Patch tested: REPLACE_WITH_PATCH_URL

 === Environment
 - WordPress: 6.9-alpha-60093-src
 - PHP: 8.2.28
 - Server: nginx/1.27.5
 - Database: mysqli (Server: 8.4.5 / Client: mysqlnd 8.2.28)
 - Browser: Chrome 135.0.0.0
 - OS: Windows 10/11
 - Theme: Twenty Twenty-Five 1.2
 - MU Plugins: None activated
 - Plugins:
   * Test Reports 1.2.0
   * WP_Query Tester 1.0.0

 === Bug Reproduction
 1. Go to General Settings
 2. Set to any language different from English with different time locales
 3. 🐞 Bug Occurs

 === Expected Results

 - The time locales should adapt to the Language

 === Actual Results
 - ✅ Issue resolved with patch. I've tested with Russian and Spanish and
 everything changes accordingly
 - ❌ Unit tests are useless (check Additional Notes)

 === Additional Notes
 1. Despite Unit tests are passing accordingly, passing test without patch
 don't break them
 2. There is another file more adequate to "Internationalization Locale
 Switches" in this path: `tests/phpunit/tests/l10n/wpLocaleSwitcher.php`
