Question about at zone transfer behaviour on slave

[Techs-yama]

Hi all,

Have a question about at zone transfer behaviour on slave server.

In case of slave zone configure and restarting named on slave server,
After the named restart, It looks like starting polling to the master
server for zone transfer by slave server.
How many seconds polling interval on this timer ?
and can i change interval value to configure it ?

Thanks and regards.
