Log: MFC r314946: Configure leap-second smearing (always). Leap-second smearing is an experimental option that may be specified in ntp.conf(5) and the -x option on the command line to spread the effect of a leap-second over an interval as specified by the leapsmearinterval config file statement. Recommended values are between 7200 (2 hours) and 86400 (24 hours). It is advised that leap-second smearing not be used for public NTP servers (https://www.meinbergglobal.com/download/burnicki/Leap\ %20Second%20Smearing%20With%20NTP.pdf). It is also advised that NTP clients not use a mix of NTP servers using leap-second smearing with NTP servers not using leap-second smearing as that could cause undefined client behaviour. Leap-second smearing was committed to ports net/ntp and net/ntp-devel by r426825 on 2016-11-22.
