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

Hi all, Was just listening to the CrowdScience on time. Thanks to whoever posted the link to it. CrowdScience indicated that a leap second was not added for the GPS. They also indicated that the GPS gives us UTC time. Question: The UTC time that the GPS gives. Does that have the leap second
