[Resolved] Show post expiry date on a page

I am trying to create a shortcode to display the CRED post expiry time, formatted as a date, on a single post.

I tried this but I get an error.
(Used this to convert other types fields before)

// Get post expiry date
// Usage: [post-expiry]

function my_post_expiry_time($atts, $content) {
	
	$epoch = get_post_meta( $post_id, '_cred_post_expiration_time', true );
	$dt = new DateTime("@$epoch");
	$my_expdate = $dt->format('Y-m-d');
	
    return $my_expdate;
}
add_shortcode( 'post-expiry', 'my_post_expiry_time' );

Dear Tina,

Please try to modify your codes as below, and test again:

function my_post_expiry_time($atts, $content) {
    $epoch = get_post_meta( get_the_ID(), '_cred_post_expiration_time', true );
    $my_expdate = date_i18n( 'Y-m-d', $epoch );
    return $my_expdate;
}
add_shortcode( 'post-expiry', 'my_post_expiry_time' );

Added a small change to check if there is a post expiry time, because I got an error..
Posting it if anyone needs this.

/* Get post expiry date */
// date_i18n is a WordPress function
// Usage: [post-expiry]
function my_post_expiry_time($atts, $content) {
	// get expiry date value
    $epoch = get_post_meta( get_the_ID(), '_cred_post_expiration_time', true );
    // check if not empty, convert to date, else return nothing
    if (!empty($epoch)) {
    	$my_expdate = date_i18n( 'Y-m-d', $epoch );
    	} else {
    	$my_expdate = '';
    	}
    return $my_expdate;
}
add_shortcode( 'post-expiry', 'my_post_expiry_time' );
