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.

I have not measured the accuracy of the clock but I expect it to lose
time. And, I never refer to it, never use it. I have a big wall
clock that above the K3 that tells me the time (actually, it does not
"tell" me the time, I have to look at it) but it loses a good minute
or two per week. I let it get as much as several minutes in error
before I bother to correct it. My watch is pretty good though. I
set it about three times a year and I have never had it more than
two-seconds from accurate Internet time. It is a Citizen EcoDrive --
