An updated system-config-date package that fixes a bug is now available for Red Hat Enterprise Linux 5.
system-config-date is a graphical interface for changing the system date and time, configuring the system time zone, and setting up the NTP daemon to synchronize the time of the system with an NTP time server.
Prior to this update, the system-config-date program set date and time in two separate steps which sometimes caused time update threads in Xen virtual machines (VMs) to become unresponsive. This version sets date and time together in one step. As a result, any Xen VMs running on the host no longer hang during the date and time update process.
All users of system-config-date are advised to upgrade to this updated package, which fixes this bug.
