Updated ntp packages that fix one bug are now available for Red Hat EnterpriseLinux 6.5 Advanced Update Support.
The Network Time Protocol (NTP) is used to synchronize a computer’s time withanother referenced time source.

This package includes the ntpd daemon whichcontinuously adjusts system time and utilities used to query and configure thentpd daemon.This update fixes the following bug:* Previously, when the ntpd daemon was configured with the “-x” option to adjustthe system clock slowly instead of changing the time instantaneously, the systemclock was incorrectly changed instantaneously when a leap second occurred.
Incertain applications, this could lead to a variety of system clock relatedproblems, such as incorrect event sorting or triggering.

To fix this bug, ntpdnow adjusts for the leap second slowly over a long interval, which prevents thedescribed problems. (BZ#1381600)Users of ntp are advised to upgrade to these updated packages, which fix thisbug.
