How to change the post date to update date in AMP

@suanlian To change the date format you can create a reader more template override for the meta-time.php file. To do so perform the following:

1. Create a folder called amp in your active WordPress themes root directory
2. Copy the meta-time.php file from the amp plugins template directory (wp-content/plugins/amp/plugins)
3. Paste that file into the newly created amp folder in your active theme
4. Edit that file by replacing the following:

   echo esc_html(
    sprintf(
     /* translators: %s: the human-readable time difference. */
      __( '%s ago', 'amp' ),
        human_time_diff( $this->get( 'post_publish_timestamp' ), current_time( 'timestamp' ) )
    )
   );

   With the following, or any other date format/prefix you prefer:
   printf( __( 'Updated: %s', 'amp' ), get_the_modified_date() );

James Osborne, Thank you! It is working perfectly!

** 2. The root is (wp-content/plugins/amp/templates) ??

Thank you!
