PC's maintain time using internal real-time clock chips. These are relatively low cost devices that do not keep very good time. They can drift by seconds or even minutes each day. This can cause real headaches when events need to be ordered across a numbe...

All computers maintain system time from an internal real-time clock chip. These devices are generally relatively low-cost and as a consequence tend not to keep good time. In fact, computers are notorious for providing inaccurate time and can drift by seve...

Do you regularly need to correct the time on your PC? The answer is probably "Yes!". This is because computers have very poor time-keeping hardware. Often, the system clock in a regular PC can drift by minutes each day. However, help is at hand. It is ver...

NTP, or Network Time Protocol, is a standard protocol for synchronising time on computers and network equipment. NTP allows client computers to synchronise with a reference NTP server over a computer network. The protocol was originally developed for the ...

The DCF-77 radio time and frequency transmission is broadcast from Mainflingen near Frankfurt, Germany. The DCF-77 signal can be used by timing equipment to provide a precise time reference. Computer timing equipment, such as NTP server systems, which pro...

A NTP Server is a network device that provides network servers and other network infrastructure with an accurate timing reference. A NTP Server obtains precise time from an external time source, such as radio time and frequency broadcasts or GPS. This art...

Computers systems have internal real-time clocks that are notoriously poor at keeping accurate time. Hence, the time on all computers and network devices can drift away from one another at different rates. This can be a real headache when trying to synchr...

A time server is a computer server that obtains precise timing information from an external hardware clock and provides this information to clients across a computer network. A time server may be located on a local network, or intranet, or may be located ...

The Network Time Protocol (NTP) was developed more than 25 years ago to synchronise Internet servers to the correct time. NTP is now one of the oldest protocols still in operation today. The protocol is widely used to synchronise Internet and intranet inf...
