This domain hosts a stratum 1 Roughtime time synchronization server implementing the latest Roughtime draft.

Hosting is provided by STUPI AB and the server tracks the STUPI UTC timescale which is generated by an ensemble of hydrogen masers and caesium clocks. Feel free to use this server as needed to perform time synchronization, timestamping, and to test and develop software for the Roughtime protocol.
