I don't know if it's what you're after, but I've been (slowly)
working on a scheduler module based on mnesia.

It's not ready, and wholly undocumented, but for those who
enjoy source-as-documentation, the work in progress can be
seen at:

http://erlhive.svn.sourceforge.net/viewvc/erlhive/trunk/lib/erlhive/src/erlhive_schedule.erl?view=markup

(It's in ErlHive, but there really isn't that much that's 
erlhive-specific about it.)

The idea is that you should be able to register calendar-like 
'appointments' - repeating if necessary - and tie them to actions that 
are fired at the right moment.
