[Elecraft] accurate time

[Dick Dievendorff]

They exist. This capability is being considered for eventual inclusion in
the K3 Utility.  But I have other K3 Utility tasks ahead of this one...

If you're impatient, you might be able to work up something based on the
commands described...

So we just need a little utility that will automate this process and 
keep the K3 "on time".
