Hardware Clock having wrong time on cluster node

The time of the hardware clock is wrong.
The server has been fenced and not shutdown in a normal way.

In /etc/sysconfig/ntp there have been added 2 new parameters:
## Type:           boolean
## Default:        "no"
#
# Force time synchronization befor start ntpd
#
NTPD_FORCE_SYNC_ON_STARTUP="no"

## Type:           boolean
## Default:        "no"
#
# Force time synchronization of hwclock befor start ntpd
# This works only if NTPD_FORCE_SYNC_ON_STARTUP is set
# to yes.
#
NTPD_FORCE_SYNC_HWCLOCK_ON_STARTUP="no"

By default these are set to "no". When set to "yes", the time will be set to the hardware clock when ntpd starts.

Normally the hardware clock will be set to the time from ntpd when the server is restarted or shut down. In a cluster environment (NCS and HAE) often these servers are fenced and no normal shutdown happens. Due to this the hardware clock will not be set to the actual time.

In addition, the hardware clock will only be updated when the difference between hardware time  and Kernel is 15 minutes or less. In case of daylight saving time switch the difference is bigger and due to that the hardware clock will not be updated by the kernel itself.

Also in /etc/sysconfig/clock the following option has to be set to "yes" (default):
SYSTOHC="yes"
