On a Linux system use your distributions software management tool to install ntpd (the official server). Edit the configuration file to use around 3 servers to synch with (see the link ctsgnb gave for a list of pools geographically near you), or just the one you have available locally. When you start the NTP server it will automatically synch with the servers you've specified, as well as provide that time to the local network for other NTP clients/servers.

ntp.conf
ntp.conf(5) File Formats Manual ntp.conf(5)
Name
ntp.conf - Network Time Protocol configuration file
Description
The file is the configuration file for the Network Time Protocol (NTP) daemon, This file must be configured on your system before running
Any host names that you specify in the file must have an entry in the file, or an entry in the master database, if the database is being
served to your system by BIND/Hesiod or Yellow Pages.
The file has four entry formats:
trusting no
This entry guarantees that your system synchronizes only to the NTP servers identified in the peer and server entries specified. Dig-
ital recommends that all systems include the entry.
peer server
This entry identifies server as one of the NTP servers that your system trusts, and from which your system will accept time synchro-
nization. Your system may also provide time synchronization to this server. Servers can be identified by host name or internet
address.
NTP servers should be configured with entries.
server server
This entry identifies server as one of the NTP servers that your system trusts, and from which your system will accept time synchro-
nization. Your system can not provide time synchronization to this server. Servers can be identified by host name or internet
address.
NTP clients should be configured with entries.
peer /dev/null LOCL 1 -5 local
This entry identifies your system as a local reference clock. A local reference clock is the most accurate system clock available at
your site. If you receive time synchronization from the Internet NTP service, you should not include this entry on any of your sys-
tems. At most, one system in a set of nodes running should be identified as a local reference clock.
A host which specifies this entry should not specify any or entries.
Examples
This is a sample configuration file for an NTP client which receives time synchronization from the NTP servers: and Lines beginning with a
number sign (#) are comments.

# This file is mandatory for the ntpd daemon

#
# ** A L L **
#
# "trusting no" prevents this host from synchronizing
# to any host that is not listed below. It is recommended
# that all hosts include the line "trusting no".
#

#
# ** S E R V E R **
#
# If you are configuring a server, use "peer" entries to
# synchronize to other NTP servers. For example, server1,
# server2, and server3.
#
#peer server1
#peer server2
#peer server3
#
#
#
#
# ** C L I E N T **
#
# If you are configuring a client, use "server" entries to
# synchronize to NTP servers. For example, server1, server2,
# and server3.

#
# If you are configuring a local reference clock, include the
# following entry and the "trusting no" entry ONLY.
