How to enable Network Time Protocol

ntpdate is a time adjusting client utility. The UC-7101/7110/7112 play the role of Time client,

and sends requests to the Network Time Server to request the correct time.

Set the time server address for adjusting the system time with the command:

/>ntpdate ntp_server_ip

Save the system time to the hardware’s real time clock with the command:

/>hwclock -w

Visit http://www.ntp/org

for a list of recommended public NTP servers.

How to update the system time periodically with Network Time Protocol

1. Create a shell script file that includes the following description.

#!/bin/sh

ntpdate ntp_server_ip

hwclock –w

sleep 100



The min time is 100ms.

2. Save and make this shell script executable by typing

chmod 755 <shell-script_name>

Edit the file ‘/etc/inittab’ by adding the following line:

ntp: unknown: /directory/<shell_script_name>
