[Elecraft] Clock Accuracy

You know, 
I always thought that the Elecraft K3 was and will always be an Amateur Radio Transceiver.
That it has a clock in it is a bonus, that it is as accurate as it is is also a bonus.

It seems to me that some of the more anally retentive of us in here want it to be a clock with an Amateur Radio Transceiver installed.

For gods sake, get over it............ Its an Amateur Radio Transceiver (And a damned good one at that!).
If you want an accurate clock so bad go and buy a cesium standard and set it up. 
(Or use a Silicon chip magazine kit that can lock almost any clock to a GPS signal.)

No, can we PLEASE go back to our normal programming???

  i used to use the windows XCP "sync by internet to NIST time" function but
  after having my computer clock set 14 seconds and 17 seconds off utc i
  ALWAYS double check and independant source...the k3 is the most convenient

  But those modes are computer generated, and the computer clock can be
  easily sync'ed with a NIST standard.  I don't know why anyone would want
  to use a free-running clock for anything that requires that degree of
  accuracy.

  The RTC in the K2 or the K3 is intended only for a logging convenience
  when no other timepiece is available.  I cannot believe it was ever
  intended to be a precision clock standard.  If you err in your log entry
  by 30 seconds, does anyone care?
