You might want to add ntpdate to maintain proper time.
ntpd, you mean. ntpdate cannot substitute for a properly configured ntpd. It is only a one-off time adjuster (usually a precursor to ntpd's startup).
+1 for ntpd.
I found out the hard way. dovecot would keep stopping in a mail server. After some investigation I correlated the dovecot stops to a cron job that ran ntpdate to adjust the system time. Installed ntpd, removed the ntpdate cron entries and dovecot worked happily thereafter.
Now I run ntpd in all my systems in "client" mode. They all point to one "server" mode ntpd on the LAN. The LAN ntp "server" references from ntp.pool.org time servers.

I am curious to know, if there is a single machine and uses ntpd as a client for the main ntp.pool.org server then suppose the internet is down, what time will the computer reference to? The reason I ask this is that my Reliance CDMA phone sets its clock on the time from the tower. When there is no signal in an area and I start the mobile, it show me 2355 at any time of the day, till it gets a signal tower. I can't let it happen in the comp.

Each computer has its own on-board clock, with its own power. Ntpd is only a way to set this clock to some reference clock's time.

Who knows? Perhaps a Reliance quirk. I don't think the mobile operators are very particular about serving accurate time to phones. I prefer to set my phone's time manually than depend on the operator.
