[time-nuts] Update on Skytraq venus8

Back in January it was reported here that the Venus 8 timing modules from Skytraq as used in the LTE-Lite, had a firmware bug that was causing the leap second to be applied as soon as the warning was seen in the GPS stream. I had bought one from Navspark  and once I reported the issue they shipped me a replacement receiver as soon as the F/W update was available. I would have preferred the new F/W, but I got a free receiver as they did not want me to return the bugged one. 

Anyhow, I just put the bad one in the drawer until today and have reconnected it to see if there were any residual issues now that the warning is gone.
Happily all is well,

I did not check what happened over the June 30 235959 July 1 00:00:00 transition.
I suspect that the device will be OK to use , with the quantization correction, until the next leap warning appears in the data stream which should give us a year at least. 

So anyone with who got a replacement can dig them out again.
