This program synchronizes the date and time of your PC with the atomic clock provided by the United States' NIST (National Institute of Standards and Technology).
It can run as a background process, performing time synchronizations at regular intervals, or execute once as part of a "CRON" batch. This will keep your clock accurate to about one second, with considerably less CPU load than NTP, using an older protocol called "DAYTIME" (well-known port 13).
