Tomorrow evening, I'm going to a leap second barbecue. The barbecue itself was the idea of a friend, but I'm bringing the equipment to show the leap second.
My main setup is a Thunderbolt, Lady Heather running on a PC laptop, and a serial to USB converter. It's all working sitting here on a desk this evening, so the only thing I can't test in advance is the leap second itself. I haven't had the Thunderbolt running during a leap second before, but there is a YouTube video showing the June 2012 leap second as handled by a Thunderbolt and Lady Heather, so I'm assuming all will work as expected. Never one to trust a single piece of hardware completely, I want to bring a backup. I have an old Garmin GPS-25 board mounted in a box with power supply and RS-232 level converters, so I want to bring it too. I have watched a leap second previously on the GPS-25, so I know it handles the event properly. But the GPS-25 is NMEA output so it won't work with Lady Heather. I need something else to display a digital clock that everyone can see, from a NMEA data stream. VisualGPS displays a bunch of interesting stuff, but not time. U-center from u-blox displays UTC as both analog and digital clock, and the analog clock can be made as large as you have screen space for. Does anyone know what it does with a leap second? Are there other programs I should look at? - Dave _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
