HI The TBolt does not directly display any date or time data. All it really puts out are PPS and 10 MHz. The rest of the stuff needs a chunk of software to make any sense at all out of. What you *really* need is a friend writing the software who is willing to drop in a auto correct routine some time before 2017.
I realize that only gives us a bit over 4 years to get on somebody's good side *and* for them to put in something less than a hundred lines of code. …. Of course it is open source, so I suppose one could fix it themselves. Somehow that sounds far to much like work.
