I've browsed a little the code for this in darwin, and I found this http://cvs.opendarwin.org/index.cgi/src/PowerManagement/pmconfigd/AutoWakeScheduler.c This means that the functionnality is meant to exists. I loose the track in the function tellPMUScheduledTime. Someone can follow up maybe. -- Cedric "[Of course] I'm French! Why do think I have this outrageous accent, you silly king-a?!"
