This article explains how the NIST radio transmission from Fort Collins, Colorado can be use to synchronize a computer network to UTC time.
This article explores the way computers all
over the world can communicate with each other using NTP and UTC time.
The world
is becoming an ever smaller place. Modern technology means that it is just as
easy to make a purchase from the other side of the world as it is buy something
from our local high street.
Everything
from hotels and airline tickets to jewellery and clothes can now be bought from
the other side of the world with just a click of mouse.
This article explains all the different time
scale utilized and how time can be synchronised globally.
Asking
somebody the time may be one of today’s most common questions but have you ever
wondered where the time on our watches comes from?
Accurate
clocks have only been around since the mid 17th century, before then,
time was completely subjective. People would use the celestial bodies as a time
reference such as noon (when the sun was highest) and midnight (when the moon
is at its highest) and also dawn and dusk. Often lengths of time were referred
to in comparison such as the time it would take a man to walk a mile.
This article attempts to explain NTP (Network Time Protocol) and how it is utilised in time servers to synchronise computer networks.
A Guide to NTP and Computer Network Time Synchronisation
Network Time Protocol (NTP) is one of the Internet’s
oldest protocols. In use for over 25 years, NTP is still under development
with version 4 currently in progress. Put simply, NTP is a computer
protocol that is used to
synchronise the clocks of computer systems; usually to an
authoritative time reference such as UTC (Coordinated Universal Time or Temps Universel Coordonné)
which became the international standard of time after the development of
atomic clocks.
