-Get process group ID (pgid) instead of process ID. It didn't work when
 it was called from cron.
-pgrep should accept full path. Without "-f" pgrep accepts "ntpd", but
 not "/usr/sbin/ntpd"

Because of the two reasons above the system_clock_monitor script was not
killing ntpd correctly.

In practice, the ntp will be killed after 10s, instead of default
timeout from ntpd 50s.

Add wrsSystemClockDriftUs (in microseconds) as int32. There is no need
to export this value as int64, with greater values of the offset
the exact information about the offset is not needed.

Don't kill other ntpd instances.

Reduce the possible range in Kconfig to the half of the possible range.
E.g. setting job to be run every 40minutes is not trivial and */40 will
not work. Instead it will run the job at minute 0, then 40, then again
at 0 (after 40min, then after 20min).

Some deamons/etc that log messages to syslog do not specify facility.level
in their messages. The logger is configured to parse the message looking
for facility.level (option: --prio-prefix). If the message does not include
If no facility.priority is specified, the logger will use the one specified
after -p, this is now provided. For example, PPSi does not specify
facility.priority in messages (hopefully, this will change), without
"-p daemon.info", it was reported as user.info. If user wishes to,
he/she can override. This is the default config

Some scripts write to files to pass information to SNMP.
To avoid read access failure from SNMP, the previous file is copied to a
.old file then the new one is created.

The system clock monitor measures the offset between the local time and
the NTP time. If this offset exceed a given threshold an alarm will be
raised .
