A fork of Google's Roughtime protocol and utilities for building Roughtime clients. This repository also implements the IETF version.
For more information about Roughtime and tips for writing your own client or server, visit the developer documentation.
This repository currently supports draft-ietf-ntp-roughtime-11 and draft-ietf-ntp-roughtime-08. Backwards compatibility with this version is not guaranteed; users should expect breaking changes as the IETF process continues. Likewise, the API should be regarded as unstable.
If you want to use this code and the protocol please join the NTP WG mailing list so that you are aware of the evolution of the protocol and issues that others discover.
DO NOT USE IN PRODUCTION SOFTWARE
We welcome pull requests for adding your Roughtime service to our list. Your PR should do the following:
Add your server's configuration to ecosystem.json. The list of servers
will be alphabetized by the "name" field.
Add some information about your service to ecosystem.md. (This is also
kept in alphabetical order.) This should include details about how your
service is provisioned:
Generate the ecosystem.json.go from the ecosystem.json. Use the
go generate command for this.
A couple things to keep in mind:
To be healthy, the Roughtime ecosystem needs a diverse set of time sources. The list already contains servers that are synced with Google's NTP servers; as such, servers that expose new sources will be preferred. (An atomic clock would be cool!)
We reserve the right to prune this list at any time. (For example, if a server is unreliable, or its root secret key has been compromised.)
As new versions come out we may prune servers that do not update.
Finally, a disclaimer: the ecosystem is growing, and ours might not be the definitive list of who is serving Roughtime at any given time.
We welcome your bug fixes, issues, and improvements to either the protocol or this code. Note that substantive changes to the protocol need to be discussed on the NTP WG mailing list.
