I don't think the WWVB signal has that much information on it. I think only
the minutes and seconds information, because of the different time zones.


The data format is available in their time standards doc, NIST Special
Publication 432. It's at their web site, somewhere in ?.nist.gov.
About a 3 megabyte .pdf, 80 pages. (Hey, I never looked at the WWVB
section before. Cool pictures of the antennas and transmitter).

There's 60 bits with minute, hour, day of year, two decimal digits of
year, and bits for leap year and daylight savings time and other stuff.
There's no seconds information, as it's sent at 1 baud and it takes
a minute to send the packet.
