Sorry Steve, That question needs a deeper understanding that I have. All I
saw was the time out by more than 3 minutes and "busy" in the little box.
I tried the "try" button but if I'm honest I was only guessing what might
do but it didn't help and I've no idea what in particular was busy.

I was surprised to find I could find a way to get the machine to fetch the
time and adjust the clock. It may well be that it's not designed to do
that.

Yes, I can see that now but it is quite frustrating not to be able to set
the clock by my choice. I don't think I've ever encountered a clock that
had that feature before in my life.

Yes, I'm sure you're right but I've never come across it before and to be
honest, I don't like the restriction.
Cheers,
Bob.
