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...

What is a time server?
A time server is a device that utilises a single time source and distributes it amongst a network. This enables all machines on a LAN (or WAN) to be synchronised together.

Microsoft Windows has a built in time synchronisation facility called windows time (w32time.exe). Windows time is based on Network Time Protocol (NTP) an Internet protocol designed to synchronise computers on a network.
Using Windows Time service it is...

This article explains how you can synchronise your computer with an absolute time source and can be kept accurate using NTP.
Clocks are essential for computers. Everything from sending and email to turning a PC on will involve a timestamp. Computers ar...

Precision and time synchronisation is highly important for modern computer networks, without synchronisation many time sensitive transactions would be impossible to carry out.
The internal clock in computers does keep time and date information but these ...
