My understanding was that leap seconds only need to be setup
on stratum-1 servers and leap seconds trickle through from those.
On my system with two refclocks non of the other servers showed a
pending leap indication until I copied leapfiles over to them in
anticipation of distributing the refclock signals to them (which
I've not had time to complete). The internet servers I use are
currently all showing as stratum2.
