Did the NIST "break" a bunch of radio-controlled (WWVB) clocks?

Figure 1:
Was  this clock - and thousands of others like it -
"broken" by a recent WWVB format change?
Shown is a SkyScan model 86715.

NOTE:

For a followup of this article, see the March 18, 2013 entry of this blog - linked here. 

Spoiler alert:  The WWVB format change is NOT responsible for this clock's no longer working - see the above link.


In case you are interested, the August 7, 2012 post - linked here - discusses the construction of an active "repeater" to relay signals from an outdoor antenna to indoor clocks so that they may reliably receive the signal from an LF time station such as WWVB.
