Time Server

Internet Time Server

A Time Server is a device connected to the network that has trusted time and responds to a computer request for time information by using one of several internet time protocols.  By far the most commonly used time protocol is the Network Time Protocol (NTP).  Other time protocols include the Simple Network Time Protocol (SNTP), Time and Daytime.

Generally what is meant by an Internet Time Server is a Time Server connected to the Internet that is available for public use.  It responds to time queries from computers all over the world.  By installing the NTP client software on each of your workstations, and then directing each of them to get their time from the Internet Time Server, you can keep your network synchronized.

This is fine as far as it goes but many IT Administrators want a dedicated time server installed inside their firewall.  Why?  There are several reasons but the main one is security.  Using an Internet Time Server means you have to open a "hole" in your firewall (UDP 123).  This brings with it a risk of attack from the outside.  With a time server inside your firewall you have control over all aspects of synchronizing your network and you can keep your firewall as intact as possible.

There are many Internet Time Servers available around the world for public use.  For a comprehensive list go to ntp.isc.org.
