POE::Component::Cron would be very nice. It can be referred to by name:
POE::Component::Cron->spawn( Alias => 'cron' );
sub handle_event {
my $kernel = $_[KERNEL];
$kernel->post( cron => crontab_add => @fields ); # like cron(8)
$kernel->post( cron => at_add => @fields ); # like at(1)
...;
}
That interface needs work, but it would be nice. The last field could
be an event name (posted back) or a sub reference (called back).

This is not so bad, really, if you take Session's name literally and
consider it a session within POE's event system. Each Child can have
one, and it acts as the object's interface to POE's features.
There's no reason why you can't do both, except that maybe it's more
than you need.
