Computers are usually exceptionally poor timekeepers. They depend on lower priced timing components which are often used in general purpose clocks and watches and are just as vulnerable to server time drift. The real-time clocks and inexpensive crystal oscillators integrated on to PC boards could cause system time to drift by several minutes every day. Nevertheless, there are software remedies available to correct time drift and maintain precise system time on your PC. This informative article about internet NTP servers describes methods which you can use to eliminate system clock drift and keep accurate time on your PC and across your network. It talks about how internet based time servers and the NTP server time protocol can be used to keep precise synchronized time on your PC.
There are a great deal of Internet-based time references which make use of the Network Time Protocol (NTP) to synchronize time clients. Internet NTP servers were designed over 25 years ago at the University of Delaware by Dr D. Mills, it continues to be among the oldest protocols in frequent use. The protocol was created to offer precise synchronization of time between time servers and clients. Internet NTP servers synchronize their time to precise external reference clocks, for example GPS, national radio time standards or accurate atomic clocks. Precise time is then passed from the internet NTP server to network clients for synchronization.
Most modern-day operating systems have built-in functions to synchronize with internet NTP server systems. Linux, Unix, Microsoft Windows XP/2000/2003/Vista and Novell all possess routines for NTP time synchronization. Normally, client-side configuration consists of offering the client with the domain name of the internet NTP server.
Windows XP/2000/2003/Vista machines can accept the IP address/domain name of an internet NTP server in the time properties/internet time tab. From time to time, the internet NTP server will be approached to get time and perform synchronization.
The Linux and Unix operating systems have a NTP daemon available from the NTP web site at ‘ntp.org’. The daemon may function as a server or client and can conveniently be configured to synchronize with an internet NTP server. The ‘ntp.conf’ configuration file includes a listing of servers which can be approached. Merely enter the IP address or domain name of an internet NTP server in the listing.
To maintain precise time on a computer system using NTP is extremely effortless. Nevertheless, there are numerous other more complicated attributes of the NTP protocol. There are numerous of security features that permit service restrictions and server authentication. Furthermore, there are many reference clock drivers accessible to synchronize NTP with an accurate external reference – offering a full-blown internet NTP server installation.
To summarise, computer systems offer notoriously poor time keeping hardware. For applications in which time synchronization of processes is important or even if you just want the correct time on your PC, standard time keeping is inadequate. The alternative is to use the NTP protocol and get your computers synchronized to some of the most precise clocks in the world.
