This page explains how to use NTP on F3RP61 according to the information from Takuya Nakamura-san.

In the first place, you need to get ntp* binaries from the BSP if you do not have them under /usr/sbin of the target filesystem.
1. Un-tar (BSP installation directory)/userland/dev/cf-rootfs-dev-1.tar.gz somewhere.
2. Move to (somewhere)/usr/sbin.
3. Type "ls ntp*" to check relevant files.
4. Copy them to (TARGET ROOT)/usr/sbin.

Then, you can start ntpd by typing as follows:

/etc/init.d/ntpd start

You can check if ntpd is running by typing as follows:

/etc/init.d/ntpd status

If NTP daemon is running, you should see something like this:

"ntpd (pid 1111) is running..."

Here is a sample file of ntp.conf:
