NTP
During 2015, Netnod worked with the PTS and the SP National Laboratory to develop the infrastructure for a more robust, nationwide time distribution service.

NTP
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.
