You can get your result by following code:

<?php $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); ?>

<?php $localeLists = $objectManager->create('Magento\Framework\Locale\ListsInterface'); ?>
<?php $timezones = $localeLists->getOptionTimezones(); ?>
<?php $locales = $localeLists->getOptionLocales(); ?>

<?php if(count($timezones) > 0): ?>
    <label><?= __('Timezone') ?></label>
    <select name="timezone" id="timezone">
        <?php foreach($timezones as $timezone): ?>
            <option value="<?= $timezone['value'] ?>"><?= $timezone['label'] ?></option>
        <?php endforeach; ?>
    </select>
<?php endif; ?>

<?php if(count($locales) > 0): ?>
    <label><?= __('Locale') ?></label>
    <select name="locale" id="locale">
        <?php foreach($locales as $locale): ?>
            <option value="<?= $locale['value'] ?>"><?= $locale['label'] ?></option>
        <?php endforeach; ?>
    </select>
<?php endif; ?>

Don't use objectmanager in your phtml file. Inject the ListsInterface class to your block construct method like below code:

public function __construct(
    ...
    \Magento\Framework\Locale\ListsInterface $localeLists,
    ...
) {
    ...
    $this->localeLists = $localeLists;
    ...
}

public function getTimezones()
{
    return $this->localeLists->getOptionTimezones();
}

public function getLocales()
{
    return $this->localeLists->getOptionLocales();
}

Now call it in phtml like below:

<?php $timezones = $block->getTimezones(); ?>
<?php $locales = $block->getLocales(); ?>

<?php if(count($timezones) > 0): ?>
    <label><?= __('Timezone') ?></label>
    <select name="timezone" id="timezone">
        <?php foreach($timezones as $timezone): ?>
            <option value="<?= $timezone['value'] ?>"><?= $timezone['label'] ?></option>
        <?php endforeach; ?>
    </select>
<?php endif; ?>

<?php if(count($locales) > 0): ?>
    <label><?= __('Locale') ?></label>
    <select name="locale" id="locale">
        <?php foreach($locales as $locale): ?>
            <option value="<?= $locale['value'] ?>"><?= $locale['label'] ?></option>
        <?php endforeach; ?>
    </select>
<?php endif; ?>

Hope this helps!
