Dear Max: I bought the software several years ago and haven't looked to see what is offered currently. My computer clock on its own is annoyingly inaccurate. And it is handy to have it set for time change just with one approving click. In searching for info about hack setting watches, I saw a Rolex for four thousand dollars. That's conspicuous over consumption at its worst. I like my fifty buck Casio every bit as well. It gains only a little over a second a month.
