function wpf_post_submission_process_meta( $field_value, $meta_key, $field_id, $fields, $form_data ) {

	// Only run on my form with ID = 443
        if ( absint( $form_data[ 'id' ] ) !== 443 ) {
                return;
        } 
	
	// If the field has a specific meta key and contains a unix time stamp,
	// use that for the post_meta value.
	if ( $meta_key === 'some_post_meta_key' && ! empty( $fields[ $field_id ][ 'unix' ] ) ) {
		$field_value = $fields[ $field_id ][ 'unix' ];
	}

	return $field_value;
}
add_filter( 'wpforms_post_submissions_process_meta', 'wpf_post_submission_process_meta', 10, 5 );
```

Remember to replace the meta key in the code above to match whatever meta key you are using as well as the form ID `443`.
