It's interesting to see the title "*Why time matters at Google*" in the blog when Androis bug 5485 has not been fixed in over two years, and most Android-based phones are 15 seconds fast, as GPS-disciplined rather than UTC. It appears only Samsung got around.... When hearing about this, Daniel Gambis at IERS told me that there was such as strong momentum to drop leap seconds (ITU, etc...), yet the "damage" is done !
