Bulk Datetime Change

Bill Erickson

<p><strong>Warning</strong> This plugin is no longer supported, and does not always work with the Gutenberg block editor.</p>
<p>I recommend using <a href="https://wordpress.org/plugins/change-last-modified-date/" rel="ugc">Change Last Modified Date</a> instead.</p>
<h4>Summary</h4>
<p>Prevent the <em>modified date</em> from changing when making minor changes to your content.</p>
<p>This plugin adds a checkbox to the Publish box, “Don’t update the modified date”.  When checked, saving your post does not update the post modified date.</p>
<p>Minor changes like adding tags or fixing typos won’t bump the modified date.</p>
<p>This plugin will <em>maintain</em> the previous modified date. It <strong>does not</strong> let you specify a custom modified date.</p>
<p>When you’re ready to publish a major content change, you can uncheck this setting before saving the post.</p>
<h4>Customization</h4>
<p>Your theme will need to use <code>get_the_modified_date()</code> to display the modified date.</p>
<p>This plugin only applies to the <code>post</code> post type by default. You can customize which post types it appears on using the <code>limit_modified_date_post_types</code> filter.</p>
<pre><code>add_filter( 'limit_modified_date_post_types', function( $post_types ) {
    $post_types[] = 'page';
    return  $post_types;
});
</code></pre>


Limit Modified Date

Prevent the "modified date" from changing when making minor changes to your content.
