June 30, 2015 will be a second longer

The International Earth Rotation Service notifies that by June 2015 a positive second of coordination is added. The sequence will be as follows:

06/30/2015 23 h 59 min 59 s
06/30/2015 23 h 59 min 60 s
07/01/2015 00 h 00 min 00 s

The difference between UTC and international atomic time:
')
from July 01, 00:00 UTC to 07/01/2015: 00 UTC: UTC-TAI = -35 s
from 07/01/2015 00 h UTC until further notice: UTC-TAI = -36 s

Coordination seconds since 1972 are added to December or June, so that the UTC time does not differ from UT1 by more than 0.9 s.

Linus Torvalds said that kernel developers are not expecting any problems with Linux this year, but there will always be problems, because every time you add a second of coordination, something new is revealed. The situation is very rare, so you can not properly test it.

The dispute about the cancellation of a second coordination has been going on for 15 years. Perhaps the problem will be solved in November of this year at the World Radiocommunication Conference in Geneva. US representatives, some ITU experts, etc., insist on the abolition of leap second. However, the debate may be delayed for another couple of decades.
