I have a similar setup: FBSD+18LVC, used the leapseconds file on an
upstream/peer server (ntp9) to set the leap bits before the event.

Today timing is good, but the leap bits are still set:

(BTW, ntp9 which uses an old Oncore UT+ did not pick up the leap event
from the Oncore, as my newer servers did, but OTOH, it did know that the
event has passed.)

Only one of my 7-8 GPS-equipped ntp servers have turned off those bits,
the rest still display them. :-(
