Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Hello, I know FreeBSD can be used with great success for timing solutions (at least two core members do it ?). has someone some performance data of the quality of system clock synchronization, while using NTPd with a GPS reveiver and a hard 1PPS signal ? More precisely : is it reasonable to hope having a system clock not farther from the GPS clock by more than 50 micro-seconds ? -- Thierry Herbelot To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
