Bruce and all... Actually, GPS time does not use leap seconds. Instead of the current 16 second offset between GPS time and UTC, there will be 17 seconds of offset on or about July 1!
BTW, a search of the web will find a video of a GPS time receiver as the last leap second happened. What fun. Tune in to WWV to listen to it happen. The hearty among you will start listening now. de Jon KF5TFJ > On Jan 5, 2015, at 12:44 PM, Bruce via BVARC <[email protected]> wrote: > > I was thinking about what I would do with the extra second.
