Default maximum time replication between master and slave databases

Hello,

I am running this query in the slave database:

SELECT EXTRACT (epoch from now() - pg_last_xact_replay_timestamp());

The maximum result is 60 seconds then the value goes to 0 and start again.
I would like to modify this value to maximum 30 seconds.

I have tried to change different parameters on the postgresql.conf in both
databases but I have not find the solution.

Anyone knows how to change this default value?

Thanks.

Regards,
Alberto.
