klokprecisie

Klokprecisie refers to the quality and reliability with which a clock indicates time. It encompasses how close the clock’s readings are to true time (accuracy), how consistently those readings can be reproduced (precision), and how well the clock maintains its performance over time (stability). The term is used across horology, metrology, and timekeeping in information and communication technologies.

Key concepts associated with klokprecisie include accuracy, precision, drift, and jitter. Accuracy is the deviation of a clock’s time from the true time. Precision is the consistency of repeated readings. Drift describes slow, systematic changes in clock output, while jitter refers to short-term fluctuations around a clock’s nominal time. klokprecisie is often expressed in units such as seconds, milliseconds, microseconds, or parts per million (ppm) and, for high-end oscillators, in parts per billion (ppb).

In practice, klokprecisie is critical for activities that rely on synchronized timing. This includes distributed computing and databases, financial trading, telecommunications networks, navigation and surveying, scientific experiments, and broadcasting. Achieving high klokprecisie involves using stable oscillators (such as OCXOs, rubidium, or cesium clocks), temperature compensation, regular calibration, and synchronization to reference clocks.

Common methods to synchronize time across systems include network time protocols (NTP) and precision time protocols (PTP, IEEE 1588). Time transfer techniques using GPS or other GNSS signals, and two-way time transfer, are also important. All high-precision clocks seek traceability to the SI second and to coordinated universal time (UTC), which is maintained by standards organizations and used as a global reference.
