Since the cronjobs runs (after defined intervals) you can register task in your component. Example

<?php
function cron_init(){
		ossn_register_callback('cron', "loaded", 'cron');	
}
function cron($cb, $type, $args){
			echo ossn_dump($args);
			//set a custom timestamp for your own component
			//as you may not wanted to run task during the interval defined. 
			ossn_cron_set_handler_last_activity('videos');
					 
			ossn_cli_output("Process started", 'success');
			ossn_cli_output("Process issue", 'warning');
					 /// your stuff here
			ossn_cli_output('Process error', "error");
}
ossn_register_callback('ossn', 'init', 'cron_init');
