X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 22 Apr 2003 18:45:56 -0000 Looking for options to keep system time moderately accurate at a site without network access. So the normal application of ntpd over IP is not viable. Dialup modem not allowed either. Definition of "moderately accurate": doesn't have to be any better than I can set my watch, travel to the site, and set the system time. It just has to eliminate "travel to the site." A GPS is one possible solution using the appropriate ntpd driver. Am not sure I can place the GPS antenna in a suitable location. A WWV receiver would be another viable option but I am not having any great success in finding a prebuilt receiver with decoder suitable for direct connection to serial port and ntpd. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
