ntpdate and ntp

There are two ways of Time Synchronization. The manual documents are too complicated to understand. I quit to read. They said that

the ntpdate program is to be retired from this distribution

 in the http://www.cis.udel.edu/~mills/ntp/html/ntpdate.html

However, for me, ntpdate is easy to use and understand. And also ntpdate has small resource of my laptop shortly, and that's it. I prefer ntpdate to ntpd.

1) ntpdate

# apt-get install ntpdate
# ntpdate europe.pool.ntp.org

or

# emacs /etc/cron.daily/ntpdate &
ntpdate europe.pool.ntp.org , and save it
# chmod 755 /etc/cron.daily/ntpdate

2) ntpd

# apt-get install ntp ntp-simple and/or ntp-server
# emacs /etc/ntp.conf &
add europe.pool.ntp.org, and save it

check status
#ntpq -p
start and /or stop ntp daemon
#/etc/init.d/ntp-server start or stop or restart
