The web page http://www.heoldesign.com/index.php?id=58 twice
refers to NTP ("High Precision PG NTP Micro Server"; "The
HEOL-T101 NTP server...") and twice refers to SNTP
("compliant with SNTP protocol"; "Timing Ethernet protocol:
SNTP V4").

Giving the manufacturer the benefit of the doubt, I would
infer that it is a genuine NTP server, and that the packets
sent over the wire comply with RFC 4330 (SNTP v4), which is
the most recent RFC to be published on the subject of NTP
and its relatives. As the RFC states, "The NTP and SNTP
packet formats are the same".
