You could fudge it. For instance, I have two cron jobs that I want to run on
alternate minutes. I give these as (in an /etc/cron.d file, thus the
userid):

*/2 * * * * userid do_the_first_thing
*/2 * * * * userid sleep 60;do_the_second_thing

There may well be an elegant way to do it, which this is not, but it does
work to stagger jobs.
