* changes
* @param retryTime
* number of seconds to wait after a failed refresh attempt
* before another attempt to refresh is made
* @param expireTime
* number of seconds secondary name server can hold information
* before it is considered not authoritative
* @param minimumTtl
* number of seconds that records in the zone are valid for (if a
* record has a higher TTL, it overrides this value which is just
* a minimum)
