That was why I proposed to ntpdate on your (upstream-free since the 29th) NTP server(s) sometime on the 30th. That would synchronise its local clock with an external accurate source, without learning the Leap Indicator. > Our plan is to disable our two stratum 1 servers, and our 3 stratum 2 > servers before the leap second turnover, but to be 100% safe we would > need to do that 24 hours before, but that would be a violation of > FINRA regulations. If you run your own straum-1 servers, can't you just opt not to configure "leapfile"? Assuming your own organisation is the only user of those servers, that is (certainly don't do that if it's a public server). After the leap second has passed, you can proceed to correct things. Your clients will then be 1s ahead of correct time, and will need to step/slew their clocks to get in sync. But maybe that's OK as far as FINRA's concerned... > It looks like the safest thing for us to do is to keep our NTP > servers running and deal with any crashes/issues.
