Slaves will poll the master at "refresh-time" and pull the zone if "serial" is 
higher at the master. 

A received NOTIFY will initiate a poll.

Some tuneabals are available in bind-9 :
min-refresh-time, max-refresh-time, min-retry-time, max-retry-time

    These options control the server's behavior on refreshing a zone (querying for SOA changes) or
    retrying failed transfers. Usually the SOA values for the zone are used, but these values are set by
    the master, giving slave server administrators little control over their contents. 

    These options allow the administrator to set a minimum and maximum refresh and retry time
    either per-zone, per-view or globally. These options are valid for slave and stub zones, and clamp
    the SOA refresh and retry times to the specified values. 

See "http://www.ipsec.nu/dns/bind9/Bv9ARM.ch06.html#types_of_resource_records_and_when_to_use_them"
( which is a copy of "The ARM book" supplied with any distribution of bind-9)
