I don't know why getting the jitter doesn't work with your box (and
quite a few other servers I tried).  The problem I mentioned was that
jitter_request() will issue a WARNING because it doesn't detect the
synchronizatin source if check_ntp is run on a big-endian system.

The sync source is found using the value of PEER_SEL(peers[i].status),
where peers[i].status (which is a 16-bit value) is read without a prior
ntohs(3).  So, on little-endian, the bytes are the wrong way round.
However, PEER_SEL() reads the low-order byte of the status field, while
it should read the high-order byte.  Therefore, it actually works on
little-endian, but not on big-endian systems.  I'll fix that in a
