Of course I do. And by the way, don't email me directly, I'm subscribed
to the list.

Yes I do use UTC. It's you who are confused.

In point of fact, I get the time from satellites, using an M12 board. So
up to 12 satellites are telling me UTC. 

I'm thinking of using libtai to sync other computers to that time on the
network. It's fast, it's easy to write a short script to to set
clockspeed/adjust, and it does an adequate job.

Don't tell me what to do. I did try using the zoneinfo/right, and strace
showed that sntpclock did in fact use /etc/leapseconds.dat. Still, the
time was out by 22 seconds. Check the archives and read the thread, if
you want.

So yes, I do know what UTC is and I'm using it. The test machine agrees
with the machine getting GPS time, and also with the other boxes synced
to it.

I can't explain why I couldn't get libtai to work with right zones and
/etc/leapseconds, but there it is.

How do you know that the time you're using is in fact correct?
