Current Time in Cisco/Scientific atlanta modems

My Motorola CM need a Time-of-Day Server not a NTP Server.
The dhcpd option time-servers ist correct when you have a Time-of-Day Server.
You can use xinetd for Time-of-Day. The Service called "Time" on udp port 37.
For NTP you must set the dhcpd option ntp-servers.

In /etc/xinet.d/time you must set in udp version disabled = no

# This is the tcp version.
service time
{
disable = yes
type = INTERNAL
id = time-stream
socket_type = stream
protocol = tcp
user = root
wait = no
}

# This is the udp version.
service time
{
disable = no
type = INTERNAL
id = time-dgram
socket_type = dgram
protocol = udp
user = root
wait = yes
}
