[Elecraft] K3 Clock loses time

[Fred Jensen]

I only vaguely remember how to find the clock display on my K3, just 
did, and it is about 1 year and a week off.  I don't remember when I 
last set it.  Likewise with the clock in the K2.  I never look at them.

I'm currently building a 40-station irrigation controller for my 
Kamikaze Gardener wife [replaces 6 aging timers in the basement] using a 
pair of Microchip PICs and the Hamstack components.  The C Library 
includes Unix-like timekeeping off the CPU clock.  It is remarkably 
accurate [fast by about a second/week], but the library has an 
adjustment function in parts/10E-8.  With that, I've gotten it to stay 
with WWV to within a second over 5 months or so.  I suppose something 
like that could be built into the K3/K3 Utility, but I really doubt very 
many people use the clock.  There have to be higher priority items on 
Wayne's K3 to-do list ... including displaying the K3 output power I can 
expect when I first tap the paddles after switching the KPA500 between 
STBY and OPER ... I hope. :-)

My not-terribly-expensive Casio analog/digital watch that I used when 
traveling for my employer [does multiple time zones] needs to be set 
whenever it needs a new battery.  Other than that, it's within a second 
or two of WWV all the time.
