/* WWVB Clock v 1.0
*
* A WWVB (NIST Time Code Broadcast) receiving clock powered by an
* Arduino (ATMega328), a DS1307 Real Time Clock, and a C-Max
* C-Max CMMR-6P-60 WWVB receiver module.
*
* This code builds on Capt.Tagon's code at duinolab.blogspot.com
* which was a great reference. Specifically, I used almost without change
* his struct / unsigned long long overlay for the received WWVB Buffer,
* which apparently in turn draws on DCF77 decoding code by Rudi Niemeijer,
* Mathias Dalheimer, and "Captain."
*
* The RTC (DS1307) interface code builds in part on code by
* Jon McPhalen (www.jonmcphalen.com)
*
* There you have it.
*
* This code supports the "Atomic Clock" article in the April 2010 issue
* of Popular Science. There is also a schematic for this project. There
* is also WWVB signal simulator code, to facilitate debugging and
* hacking on this project when the reception of the WWVB signal
* itself is less than stellar.
*
* The code for both the clock and the WWVB simulator, and the schematic
* are available online at:
* http://www.popsci.com/diy/article/2010-03/build-clock-uses-atomic-timekeeping
*
* and on GitHub at: http://github.com/vinmarshall/WWVB-Clock
*
* Version 1.0
* Notes:
* - No timezone support in this version. UTC only.
* - No explicit leapsecond (3 frame marker bits) support in this version.
* - 24 hour mode only
*
