You could set "sig-validity-interval to 30 29;” if you want to see things happen
faster.  This causes the RRSIGs to have a 30 day validity interval and be 
re-signed
29 days before that expires.

Remember with DNSSEC you never move onto the next step without checking that the
last step completed first.  The next step can always be stalled.  This applies 
to both
online and offline signing.  There are lots of “wait until xxx” in DNSSEC 
maintenance.
Don’t schedule multiple steps at once.  Even with a single machine unexpected 
events
can happen.
