How would I use this filter to change the output of the date format to "Twitter time"?

Question

I'm using a plugin called Latest Tweet Widget to display the latest tweet. The tweet date gets displayed by the month and day (Mar 22). However, I want it to be in "Twitter time" meaning words like "3 days ago, 1 hour ago, etc.".

I asked the developer of the plugin at the WordPress forums and he said that I need to "use the latest_tweets_render_date filter to perform my own relative date representation."

The filter in question is here under the "Custom HTML" section (also quoted below): https://wordpress.org/plugins/latest-tweets-widget/other_notes/#Theming

add_filter('latest_tweets_render_date', function( $created_at ){
    $date = DateTime::createFromFormat('D M d H:i:s O Y', $created_at );
    return $date->format('d M h:ia'); }, 10 , 1 );

However, I am new to PHP and unable to understand what exactly needs to be written in order for "Twitter time" to work. Can somebody please show me the way?

WordPress has a core function human_time_diff that does what you want, using it with the filter you provide you have someting like so:

add_filter('latest_tweets_render_date', function( $created_at ){
    $date = DateTime::createFromFormat('D M d H:i:s O Y', $created_at ); 
    return sprintf( '%s ' . __( 'ago' ), human_time_diff( $date->format('U') ) );
});
