Subject: Leap Second Date: Tue, Jul 02, 2013 at 10:23:58AM -0400 Quoting Todd S (todd () borked ca):
We found we got leap seconds added on some systems over the weekend.  There
were no leap seconds planned (
http://www.usno.navy.mil/USNO/earth-orientation/leap-second-announcement),
however some of our systems got one.

We run our own s2/s3/s4 system, with only the s2s going to the Internet.
 We have about 20 servers defined there, but looking through the logs, I
can't figure out which one(s) may have been advertising the leap second.  I
went through all our systems on Friday and Saturday to check for the leap
bit, but had nothing, so it must have come out on Sunday.

Anyone else run in to this, or have any further intel about servers that
advertised the leap second?

We did get an advisory from Infoblox about a bug in "NTP servers based
on open source NTP" that would do just that. For Infoblox NIOS there
was a hotfix, and Symmetricom also has a patch out.
