The World Needs More Roughtime

It does! So I bring to you a public Roughtime server: port 2002

The server runs roughenough (no surprise) on a Google Compute Engine instance in us-central1.

Time is sourced from Google’s public NTP servers which conveniently implement the 24-hour leap second smear required to provide “Roughtime UTC” as specificed in the protocol definition.

Public Key


That’s the server’s long-term public key which is also stuffed into a DNS TXT record should you need it, along with a superfluous SRV record just for fun:

$ dig -t txt
