Take the 2-minute tour ×  Apparently the IERS have announced a
leap second due at midnight, June 30th this year.  Is
CentOS/RHEL 5.4 properly updated to support/transition along

would need an updated tzdata package but wasn't sure.   I
checked the change-log for the tzdata package and noticed the
following:  * Tue Feb 27 2007 Petr Machata <pmachata@redhat.com>
