But I would like to make some additional suggestions. There is no need to use multiple pools. You only need one. Pool works by using the minclock and maxclock values to work out how many peers it needs to add and keep track of. minclock is the minimum amount of * and + peers it should keep, and maxclock is the maximum amount of total peers including the actual pool itself. Also the local clock has been deprecated in favour of orphan mode. So I would suggest something like this instead: pool 0.freebsd.pool.ntp.org iburst tos minclock 3 maxclock 6 orphan 6 This will fire up a pool association and then add 5 peers from that pool and keep a minimum of 3 in * or + modes. If any become unreliable it will add more according to the min/maxclock values.
