TimeNL - Network Time Security (NTS)

Read about NTS here:

• IETF RFC8915

The original pilot server nts1.time.nl is still available as a server for experiments.

⚠ It's not recommended to use that server in a production environment!

Instead, use ntppool1.time.nl and ntppool2.time.nl in your production environment.

The experimental NTS server (nts1.time.nl) currently runs Chrony 4.5-1ubuntu4.2 in a special configuration that is NOT SUITABLE for serious use!

On another server, ntpd-rs.sidnlabs.nl, we currently run an experiment with Version 1.7.0-alpha.20251003, an NTP/NTS server written in Rust, able to take part in an NTS pool (yes, NTS, not NTP). The one we run also has NTPv5 enabled. More specific, with 'draft-ietf-ntp-ntpv5-06' in the Draft Identification Extension Field.

Go to time.nl for further information about our TimeNL public service.

Or visit ntpinfo.sidnlabs.nll for our experimental NTP checker.
