No, it's not. 

NTPd is simply reporting to the log file that eth0 is no longer valid, and it's 
removing it as the interface that it will use for querying ntp servers. ntp 
does not, and will not bring down or bring up a network interface. ntpd is at 
the same level as a mail server. It's a server application that sends and 
receives packets. It does however, keep track of available/valid network 
interfaces, and can be configured to use different ntp sources, depending on 
what interface is available. So it makes sense that it takes note of eth0 not 
being valid. It makes no sense to assume that ntpd would in any way bring up or 
down an interface.
