ntp leap-leapseconds support.
r289421:
Add default leap-seconds file. This should help ntp networks get the
leap second date correct
Updates to the file can be obtained from ftp://time.nist.gov/pub/ or
ftp://tycho.usno.navy.mil/pub/ntp/.
r293037:
Update leap-seconds to latest. This will satisfy the ntpd leap-second
version check.
r294773:
Add support for automatic leap-second file updates.
The working copy of leapfile resides in /var/dbntpd.leap-seconds.list.
/etc/ntp/leap-seconds (periodically updated from ftp://time.nist.gov/pub/
or ftp://tycho.usno.navy.mil/pub/ntp/) contains the master copy should
automatic leapfile updates be disabled (default).
Automatic leapfile updates are fetched from $ntp_leapfile_sources,
defaulting to https://www.ietf.org/timezones/data/leap-seconds.list,
within $ntp_leapfile_expiry_days (default 30 days) from leap-seconds
file expiry. Automatic updates can be enabled by setting
$daily_ntpd_leapfile_enable="YES" in periodic.conf. To avoid congesting
the ntp leapfile source the automatic update randomized by default but
can be disabled through daily_ntpd_avoid_congestion="NO" in
periodic.conf.
r294884:
Allow specification of fetch options for ntp leap-seconds fetch.
