The network time server on the LAN, WAN, or Internet may be specified by IP
Address or by Host Name.
Specifying by IP Address is typically only safe if the address of the server
is under your IT group‟s control. When specifying time servers on the
Internet, use the Host Name.
Specifying by Host Name requires that a DNS server is accessible to the
clock:
If IP addressing is static, the DNS servers must be identified and
configured as well.
If IP addressing is via DHCP, the DNS servers are typically already
automatically configured (do not over configure!)
The process for specifying a time server is the same for both Host Name and IP
Address.
1.
Log into the OnTime Clock.
2.
At the prompt, type:
sntp –h.
3.
Press the spacebar.
4.
Enter the Host Name or IP Address of the time server.
5.
Press the Enter key.
It is always a good idea to test the synchronization between the clock and the
time server. To do that, perform these steps:
1.
At the prompt, type:
sntp -s
(Be sure there is a space between sntp and -s)
2.
Press the Enter key.
The clock displays SNTP settings and immediately attempts synchronization
with the specified host (either the Host Name of the time server on your network
or with an outside time standard).
The default time server is set to
ntp.inovasolutions.com
. In general, this setting
should be changed to an internal time server under IT control. There is more
information on NTP, SNTP and time server selection online at the OnTime FAQ.
Coordinated Universal Time (UTC) is a time standard based on the time at zero
degrees longitude (also known as Greenwich Mean Time or GMT). Time zones
around the world are expressed as positive or negative offsets from UTC. The
