Indeed. This is kinda offtopic but if you put a cron running with a loop you will kill your server. I would recomend use libevent + ALARM signal to process on a time basis. On the other hand using C would be a nice aproach since you can put your script on an sleep mode until the next alarm signal is trigered + less resources taken
