	Normally, using two upstream time servers is the worst possible 
thing you can do, see 
<https://ntp.isc.org/bin/view/Support/SelectingOffsiteNTPServers#Section_4.3.3.>. 
In your case, you've got two local refclocks that you're trying to 
use, and I don't know if you're attempting to use them correctly.

	That's based on kernel 2.6, right?  If so, then see 
<https://ntp.isc.org/bin/view/Support/KnownOsIssues#Section_8.2.3.>.
