Hello!

You can add this code to the functions.php file of your child theme:

if ( ! function_exists( 'ywcars_format_datetime' ) ) {
	add_filter( 'ywcars_datetime', 'ywcars_format_datetime' );
	function ywcars_format_datetime( $post_date ) {
		return date( get_option( 'date_format' ) . ' ' . get_option( 'time_format' ), strtotime( $post_date ) );
	}
}

It will show the date and time format you have set in your WordPress settings.

All right, it works perfect, thank you

Now the other date of the field of send messages?
