Not really. If you know how to write C, you can use the
timer on the BBB and get to sub-us accuracy levels (IIRC ~10ns).
The biggest problem would be to get the data into ntp
in the right way, as I am not sure whether ntp supports
that kind of input. But I know at least someone working
on this.

The rpi has, AFAIK, no timer units
