No, it doesn't work that way at all. When you are a slave server, you periodically
refresh your copy of the zone and serve that data up directly up to clients. A slave
server doesn't send the query off to some other server to be resolved. What you seem
to be thinking of is "forwarding", but that doesn't work either since
nameserver-to-nameserver queries are typically non-recursive, and non-recursive
queries are never forwarded.

TTL has no effect on how often a slave refreshes from the master.
