Fortunately there are alternatives to using the internet as a timing source.
The most common, secure and accurate method for receiving timing source is the GPS system Global Positioning System.
Unfortunately however, there are draw backs in using the Internet for a timing source.
These time servers receive a timing source from either a national radio broadcast(such as WWVB in the US or MSF in the UK) or via the GPS system.
Arrange your network into strata. Stratum levels signify the distance from a timing source.
Traditionally many more people opted to receive a timing source from either across the Internet or via specialist national time and frequency transmissions.
Authentication is a security measure used by NTP to check that timing source is genuine.
Stratum 2 devices are machines that receive their timing source from a stratum 1 server but stratum 2 devices can also be used to pass on timing information.
It usually takes about five minutes(five good samples)until a NTP server is accepted as a timing source.
NTP(Network Time Protocol)has an inbuilt security measure called authentication that ensures a timing source is exactly who it says it is, this can't be utilised over the Internet.
The primary difference between most dedicated time servers is in the way they receive a timing source.
The timing source for an NTP server can either be taken from a specialist radio transmission that are broadcast from national physics laboratories or from the GPS network.
Radio clocks are really another term for a networktime server that utilises a radio transmission as a timing source.
When synchronising a a network it is preferable touse a dedicated NTP server that receives a timing source from an atomic clock either via specialist radio transmissions or the GPS network.
Radio clocks are really another term for a network time server that utilises a radio transmission as a timing source.
Once received the NTP server distributes the timing source across the network and constantly checks each machine for drift In essence the networked machine contacts the server as a client and the information is exchanged via TCP/IP.
Whilst not available everywhere and quite susceptible to local topography the broadcastsdo provide a secure method of receiving timing source.
Stratum 2 and stratum 3 devices can also be used as a time servers andin this way a single GPS time server can operate as a timing source for an unlimited amount of computers and devices as long as the hierarchy of NTP is followed.
A computer network using a NTP time server can use either a radio transmission orthe signals broadcast by GPS satellites(Global Positioning System) as a timing source.
Put simply, the NTP daemon(a service program that runs in the background)compares the time on the computer with the timing source at regular intervals and adjusts it depending on any drift.
Fortunately stratum 2 timeservers can offer decent enough accuracy as a timing source and any device receiving a time signal can itself be used as a time reference a device receiving time from a stratum 2 device is a stratum 3 server.
The Internet is probably the most common sources of UTC time(Coordinated Universal Time), however,using the Internet as a timing source can be a cause for several time server problems.
The body clock adjusts itself every day to ensure it is synchronised to the rotation of the sun just as a NTP time server synchronises a computer's systemclock to ensure it is running accurately to its timing source- the atomic clock.
It is far safer to receive a time signal from a radio signal broadcast by several national physics laboratories or even the GPS network whose onboardatomic clocks can be utilised as a timing source if the NTP time server is fitted with a GPS receiver.
