I have not seen this information posted to this newsgroup.  The US
NIST radio station WWVB will be changing it's transmission format.  The
information can be found at:

http://www.nist.gov/pml/div688/grp40/wwvb.cfm

The old format is still being sent twice a day until the end of
January 2013, but the station will only transmit the new phase
modulated time code after this month.  It is supposed to be compatible
with the existing 'Atomic' clocks, but I have some of the original
ones that were made in China that are no longer syncing.
