timestamp off by xx seconds

I've been getting these recently, is it anything to be worried about ?

Your "cron" job on gentian
/usr/local/libexec/dcc/cron-dccd

produced the following output:

ADMN FLOD RESUME: rejected ADMN FLOD RESUME request; timestamp off by 36 seconds

These servers are all ntp'ed up, and the time's looking healthy enough:

I'm not quite sure about where to start diagnosing this problem, so I'd 
appreciate any input.
