Issue with Minumum Value for named9

[Robert JR]

Dear All, 

i have the minimum value in my dns server as 60 mins,
and my TTL is 60 Seconds , but still when users hit a non exist record ,
the other dns hold the negative cache for 60 secs instead of 60 mins ..
? why ? 

$TTL 60
@ IN SOA NS1.TEST.BIZ. Abuse.TEST.BIZ. (
 201208281 ;
serial, todays date + todays serial #
 8H ; refresh, seconds
 2H ;
retry, seconds
 4W ; expire, seconds
 1H ) ; minimum, seconds
;


Although my configuration above, all DNS servers that query my server,
cache the non exist record for 60 seconds only and not 60 mins
As
mentioned in my configuration ? any ideas why ? 

Thanks Again 

Robert
