Does not "needing good time sync" imply communications with the outside 
world? So wouldn't those items fail for other reasons if NTP wasn't up yet? 
Ideally things that need quality time *and* connectivity would wake up when 
both conditions came true, and take some other action when connectivity was 
removed. It would be desirable for applications to be able to register to 
be notified of these events.
