Doc Text:
Time reckoned by Earth's rotation drifts away from atomic time because of irregularities in the Earth's rate of rotation. For this reason, on 30 June 2015 at precisely 23:59:59, a leap second will be inserted (23:59:60), which will be followed by 00:00:00 the next day.

Description daniel 2015-01-14 08:25:41 UTC
+++ This bug was initially created as a clone of Bug #1180536 +++

On June 30th at precisely 23:59:59, the world’s atomic clocks will pause for a single second.

Or, to be more precise, they’ll change to the uncharted time of 23:59:60 before ticking over to the more worldly hour of 00:00:00 on the morning of July 1st, 2015.

This addition of a leap second, announced by the Paris Observatory this week, is being added to keep terrestrial clocks in step with the vagaries of astronomical time in this case, the slowing of the Earth’s rotation.

Any specific reason that this BZ is private? I suggest having it be public if you see fit as we will certainly get lots of customers looking to see if Red Hat is addressing this issue.

+ 1 (should be public BZ).

I find previous all BZ related to it were private only so may be there is some reason for it?

(BZ#782174, BZ#782173, BZ#782172, BZ#773755)

I do not see BZ for RHEL 5 so filed (1181933).
