While I am truly fond of analog clocks, certainly including sundials, I also have a place in my heart for interesting digital clocks. Hence, I still have two Heathkit "Most Accurate Clocks," model GC-1000, that run 24/7 and have done for 30 years. This red LED digital clock sets its time from

Thanks to all who replied to my questions about the time on GPS. The reason I asked about the leap second. Is if the following analog clock GPS driver included the leap second correction. Yes it would. http://www.altronics.com.au/p/k1129-gps-synchronised-clock-kit/ It also corrects it for

Hi Roderick: GPS time is continuous, that's to say there are no leap seconds or other changes to it since it started. It uses a 10 bit binary week counter so the week number rolls over after 1024 weeks. This causes problems for GPS receivers that are more than a few years old since they have

Yes. The navigation message transmitted by GPS satellites includes the current leap second offset so a receiver can compute and display correct UTC. -- Richard Langley Sent from my iPhone On Jan 29, 2017, at 6:05 PM, rodwall1...@gmail.com
