style='font-size:12.0pt'>You *can* because you have full access to the servers,
however understand that any upgrade will overwrite the configuration file. See
CSCsb66270. It is very important for your CM servers to be time synched,
even if it's the wrong time. This is why the basic recommendation is:<br>
1. all subs synch to pub<br>
2. pub *may* sync to another clock source.<br>
<br>
It's generally not a good idea to sync all servers independently because of the
variations that become possible (different ntp sources, ...)<br>
