If you run an NTP server, your "syspeer" is the upstream time
server to which you are synchronized. Whatever their stratum is,
yours is theirs plus one. If they are Stratum 1, then you are
Stratum 2. If they are Stratum 5, then you are Stratum 6.
This race ends at 15 -- Stratum 16 is defined to be the
equivalent of completely unsynchronized.
If you read the official documentation (see
<http://www.eecis.udel.edu/~mills/ntp/html/index.html>) and the FAQ
(see <http://www.ntp.org/ntpfaq/NTP-a-faq.htm>), you should be able
to find the answer to this and other questions. You may also be
interested in the Community Supported documentation provided as a
part of the NTP Public Services Project at
