Product Information

Specifications:

• Product Name: Cisco IoT FND and TPS servers
• Functionality: Time and Timezone synchronization using NTP
  Service

Product Usage Instructions

Setting the Time and Timezone Using NTP Service:

Use the following steps to synchronize the time between the host
VM and the docker:

1. Run the command to edit the chrony.conf file:
   Example:

   [root@iot-fnd ~]# nano /etc/chrony.conf

2. Enter the IP address of the NTP server you want to use in the
   chrony.conf file:
   Example:

   server 209.165.200.225

3. Save the changes, exit, and restart the chrony service:
   Example:

   [root@iot-fnd ~]# systemctl restart chronyd

4. To view the configured NTP server, use the following
   command:
   Example:

   [root@iot-fnd ~]# chronyc sources

Frequently Asked Questions (FAQ)
