Keeping Sweden in sync - NTP is the most commonly used protocol for synchronizing the time on computer systems. An accurate, NTP-based system is essential not only for individual users but also for local and national economies.

The Swedish national time scale is produced by the SP National Laboratory for Time and Frequency. It is distributed to the community using high-performance Network Time Protocol (NTP) servers operated by Netnod at Internet exchange points throughout Sweden.
