Adds two template tags, <code>latest_post_date()</code> and <code>latest_post_modified_date()</code>, the first echoes the most recent post publication date, the second echoes the modification date of the most recently modified post.
Each template tag takes two params: $date_format, standard <a href="https://codex.wordpress.org/Formatting_Date_and_Time" rel="nofollow ugc">WP date formatting string</a> (defaults to the default date formatting for your WP blog), and $echo, display the date, if <code>TRUE</code>, or return the date to be used in PHP, if <code>FALSE</code>, (defaults to <code>TRUE</code>).
For example: <code><?php latest_post_date( 'l, F j, Y', TRUE ); ?></code> would return a date similar to Friday, September 24, 2004 for use in PHP. Another example: <code><?php latest_post_date(); ?></code> would echo a date in the default formatting for your WP blog.
Is this plugin lacking a feature you want? I’m happy to discuss ideas, or to accept offers of feature sponsorship: <a href="http://www.simonwheatley.co.uk/contact-me/" rel="nofollow ugc">contact me</a> and we can have a chat.
