start ntpd with launchdaemon I would like to start an ntpd on my MacOSX 10.8. ntpd is configured correctly and runs when started manually. 
I would like to start it on boot time with lauchdaemon.

I created this com.stefan.ntp.plist file in /Library/LaunchDaemons:

&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"&gt;
&lt;plist version="1.0"&gt;
    &lt;dict&gt;
        &lt;key&gt;Label&lt;/key&gt;
        &lt;string&gt;com.stefan.ntpd&lt;/string&gt;
        &lt;key&gt;Program&lt;/key&gt;
        &lt;string&gt;/usr/sbin/ntpd&lt;/string&gt;
        &lt;key&gt;ProgramArguments&lt;/key&gt;
        &lt;array&gt;
            &lt;string&gt;&lt;/string&gt;
        &lt;/array&gt;
    &lt;/dict&gt;
&lt;/plist&gt;


Added it to the Launchdaemon with

launchctl load /Library/LaunchDaemons/com.stefan.ntpd.plist


However, it does not start. 

sh-3.2# launchctl list | grep ntpd
-   0   com.stefan.ntpd
sh-3.2# launchctl start com.stefan.ntpd
sh-3.2# launchctl list | grep ntpd
-   0   com.stefan.ntpd


Any ideas?
There should be an ntpd process started by /System/Library/LaunchDaemons/org.ntp.ntpd.plist by default in 10.8.

The plist is also missing &lt;key&gt;RunAtLoad&lt;/key&gt;&lt;true/&gt;, but I couldn't get this to work either:

&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd"&gt;
&lt;plist version="1.0"&gt;
&lt;dict&gt;
  &lt;key&gt;Label&lt;/key&gt;
  &lt;string&gt;com.stefan.ntpd&lt;/string&gt;
  &lt;key&gt;Program&lt;/key&gt;
  &lt;string&gt;/usr/sbin/ntpd&lt;/string&gt;
  &lt;key&gt;RunAtLoad&lt;/key&gt;
  &lt;true/&gt;
&lt;/dict&gt;
&lt;/plist&gt;
