2015-01-05 Leap second announcement
Promptly after fixing the previus leapsecond file I get the IERS Bulletin C number 49 today which states:
                                   UTC TIME STEP
                            on the 1st of July 2015


 A positive leap second will be introduced at the end of June 2015.
 The sequence of dates of the UTC second markers will be:

                          2015 June 30,     23h 59m 59s
                          2015 June 30,     23h 59m 60s
                          2015 July  1,      0h  0m  0s
And I notice the IETF seems to update the canonical leap-seconds file about two months after the decision is made by the IERS.

It's a good thing ntpd starts complaining when the file is about to expire.

Update 2015-01-06: An update was available from ftp://time.nist.gov/ but only when I connected over IPv6. An interesting form of IPv6 promotion. Notice the difference in messages between the old file and the new file loading:
