No. Unfortunately you can't get seconds granularity with cron

No need for a nasty kludge like that. Needless to say, a fully-featured scheduling framework is quite able to cope with every n seconds - it's just that *cron* is not designed to support that
But you definetely don't need the whole scheduling framework to send emails after every certian interval
