Configuring SNTP
 | Simple Network Time Protocol (SNTP) enables you to adjust the system clock by using the time server on the network. The protocol is typically used for synchronizing the machine and a server, such as when the machine needs to access an LDAP server with the security authentication that was enabled. The time is adjusted based on Coordinated Universal Time (UTC), so specify the time zone setting before configuring SNTP (Date/Time Settings). SNTP settings can be specified via the Remote UI. |
 |
The SNTP of the machine supports both NTP (version 3) and SNTP (versions 3 and 4) servers. |

[NTP Server Name]
Enter the IP address of the NTP or the SNTP server. If DNS is available on the network, you can enter a host name (or FQDN) of up to 255 alphanumeric characters instead (example: ntp.example.com).

Testing communication with the NTP/SNTP serverYou can test whether the machine is communicating with the registered time server via SNTP. Go to [Settings/Registration] [Network Settings] [TCP/IP Settings] and click [Check NTP Server] in [SNTP Settings]. If a proper connection has been established, the result is displayed as shown below. Note that this operation does not adjust the system clock. |
