This is beginning to sound like the saying that the man with two wristwatches never knows what time it is. Pick a 'time standard' that is appropriate for you - Cellphone time or Atomic clock as your time for skeds (those are quite accurate) as well as the time standard from WWV. The K3 clock can be reserved for those times when access to those other time standard sources are not available (such as Field Day and other similar occasions).

The K3 RTC depends on the crystal and the associated capacitors. It is not a precision device, but is more than sufficient for logging purposes for outings where it is the main source of time stamping - assuming it is set correct at the beginning of the outing.

My Timex watch seems to be quite accurate - I have not had to reset it in the last 3 months! In other words, I would not depend on the clock in the K3, KX3 or the K2 to be more accurate than my Timex. The need for time precision to the second is overrated IMHO - logging QSOs to the nearest minute seems to be acceptable, accuracy to the second is not required for logging purposes.

My K3 clock loses about 9 seconds per day. This is not quite as bad as Arlen's 
clock, but it is still annoying. I run quite a few skeds and nets and I like to 
be spot on time.
