        <description>leap-seconds: Update to leap-seconds 3960057600 obtained from IERSIERS is the canonical source of leap-seconds. IANA, NIST and USNO obtaintheir leap-second updates from IERS.This resolves an issue for IPv6-only hosts as IERS is not accessiblevia IPv6, requiring IPv6-only host to rely on some other source,above.From this point forward we should fetch the file from IERS, theorganization responsible for deciding when to insert leap-seconds.PR:		279413Obtained from:	https://hpiers.obspm.fr/iers/bul/bulc/ntp/leap-seconds.listDiscussed with:	impMFC after:	1 day
