[time-nuts] Re: Crazy Clock

[Bob Camp]

Hi

Indeed that gets me part of the way there. It at least moves the task from building a
clock over to feeding an existing gizmo the type of time I want to see.

What I want to display is actually the time that GPS runs on. The formal name appears
to be GPS System TIme. UTC without leap seconds is another common way of talking 
about it. 

Since you are off from the “rest of the world” by some number of seconds, you can’t just 
sync up to a typical source and move on. Somehow you need to deal with the (variable 
over long time spans) offset between GPSST and UTC. 

The “why?” behind this is that I’m in the middle of a bunch of GPS based file this and 
that. They all sync up to GPSST. Checking on them to see that all is well involves 
working out when they should have done this or that. Having a clock to look at should
make that easier.
