a way that, if a time server does misbehave, clients end up with cryptographic proof of it. It was
created by Adam Langley and Robert Obryk.

### Public int08h.com Roughtime Server
A publicly accessible Roughtime server is available at `roughtime.int08h.com` port `2002`. The
server's long-term public key is `016e6e0284d24c37c6e4d7d8d5b4e1d3c1949ceaa545bf875616c9dce0c9bec1`
and can verified by querying the server's DNS `TXT` record:
```bash
$ dig -t txt roughtime.int08h.com
...
;; ANSWER SECTION:
roughtime.int08h.com. 1799 IN TXT "016e6e0284d24c37c6e4d7d8d5b4e1d3c1949ceaa545bf875616c9dce0c9bec1"
```
