I wouldn't use ntpdate on the same machine, but if I did, I would use -d
as it gives more information and is documnented as not using port 123 as

This value is not possible.  Precision is always a power of two and
generally a relatively large negative power.  I suspect you have
a broken protocol analyzer.

Estimated error.  The drop dead value is about 1.0 (and that is 
after adding root distance).

is sending this value.
