Overview
Most computer clocks are not very accurate, they easily gain or lose seconds as time goes on. This may not seem like very much, but after only a few days or weeks, these seconds could build up to many minutes, even hours and days in some cases. This inaccuracy in keeping time could cause the computer's clock to give false time readings.
Although these problems are usually caused by faulty hardware or a low clock battery in the CPU, Nuclear Clock can correct these problems by readjusting your clock to the correct time. Nuclear Clock keeps your computer's clock synchronized and running on the correct time by downloading the correct time from Internet time servers while your computer is connected to the Internet.
Most of the time servers that are listed by default with Nuclear Clock are managed by NIST (
National Institute for Standards and Technology). NIST time servers are synchronized by atomic oscillators, which keep their clocks accurate within a few milliseconds. For more information on NIST time service, visit their website at:http://www.boulder.nist.gov/timefreq/index.html
Nuclear Clock downloads the time using the Time protocol, as specified in
RFC 868.
