Write the mcron job for a local installation of mcron first for
testing purposes, then move it into config.scm. That's how I do it.

mcron --schedule=count gives you a listing of each scheduled job and
when it will next be run. I would expect "herd schedule mcron" runs
that command. I don't know about scheduling a function, but
if the scheduled job is a string it can be copied/pasted into a
terminal.
mcron is super buggy in my experience. If I power my laptop off
overnight it will skip all jobs scheduled for the day of the month,
even if they are scheduled for after I power it back on. And it doesn't
have a way to easily schedule for a given day of the week.
