The leap smearing in NTPsec is: 1) Broken. 2) Not Google compatible. It occurs in the interval _before_ the leap second, not _centered on_ the leap second as Google has proposed.
#1 is specific to NTPsec. I submitted a Merge Request to fix this plus some whitespace inconsistencies I found while debugging: https://gitlab.com/NTPsec/ntpsec/merge_requests/671 #2 is inherited from NTP Classic, so I filed bugs on both: https://gitlab.com/NTPsec/ntpsec/issues/475 http://bugs.ntp.org/show_bug.cgi?id=3481 Given that leap smearing seems to be converging on Google's approach, I'm very hesitant to enable this feature when it is incompatible. -- Richard
