tsclockserver command with NTP server

[Anonymous]

We have been testing an NTP server. I used the tsclockserver command within a Brocade 12K and specified the IP address of the NTP server. It appears that the 12K queries this server approx. every 60 seconds. This seems a bit excessive. Has anyone else had this issue or know of a way to specify the switch to only check every hour or two?
