The D60 supports the Simple Network Time Protocol specified in RFC-2030. With SNTP, the D60 can obtain clock time
over an Ethernet network. The D60 acts as an SNTP client to receive time values from an SNTP/NTP server, usually a ded-
icated product using a GPS receiver to provide an accurate time. Unicast SNTP is supported. The UR-series relays do not
support the broadcast, multicast or anycast SNTP functionality.
The setting enables or disabled the SNTP feature on the D60.
SNTP FUNCTION
To use SNTP,

is "Enabled", the D60 attempts to obtain time values from the SNTP/NTP server. Since many time values are

obtained and averaged, it generally takes three to four minutes until the D60 clock is closely synchronized with the SNTP/
NTP server. It takes up to two minutes for the D60 to signal an SNTP self-test error if the server is offline.

The UR device maintains two times: local time and Universal Coordinated Time (UTC). Local time can be provided by IRIG-
