Synopsis
chrony bug fix and enhancement update
Type/Severity
Bug Fix Advisory
Topic
An update for chrony is now available for Red Hat Enterprise Linux 7.
Description
The chrony suite, chronyd and chronyc, is an advanced implementation of the Network Time Protocol (NTP), specially designed to support systems with intermittent connections. It can synchronize the system clock with NTP servers, hardware reference clocks, and manual input. It can also operate as an NTPv4 (RFC 5905) server or peer to provide a time service to other computers in the network.
For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the References section.
Users of chrony are advised to upgrade to these updated packages.
