/etc/conf.d/ntp-client - setting ntp-client upstream serversNTPCLIENT_OPTS="-s -b -u \ 0.pool.ntp.org 1.pool.ntp.org \ 2.pool.ntp.org 3.pool.ntp.org"
Server
The ntpd server is also an ntp-client of upstream servers. Ntpd continuously, and gradually synchronizes the local clock.
/etc/ntp.conf - setting ntpd upstream servers# Pools for Gentoo users server 0.pool.ntp.org server 1.pool.ntp.org server 2.pool.ntp.org server 3.pool.ntp.org
Runtime
root # rc-update add ntpd root # rc-update add ntp-client root # rc
Hardware Clock
To write your NTP sync time to the hardware at shutdown, and read hw clock at start.
root # echo 'clock_hctosys="YES"' >> /etc/conf.d/hwclock root # echo 'clock_hctosys="YES"' >> /etc/conf.d/hwclock root # rc-service hwclock restart root # rc-update add hwclock boot
