Fixed In Version: ntp-4.2.6p5-3.el6_6
Doc Type: Bug Fix
Doc Text:
Previously, when the ntpd daemon was configured with the "-x" option to adjust the system clock slowly instead of changing the time instantaneously, the system clock was incorrectly changed instantaneously when a leap second occurred. In certain applications, this could lead to a variety of system clock related problems, such as incorrect event sorting or triggering. To fix this bug, ntpd now adjusts for the leap second slowly over a long interval, which prevents the described problems.
