Initial release with support for WWVB, DCF77, and Junghans's proprietary format.
WWVB's amplitude modulated signal is fully implemented, but its phase modulated signal currently has some unsupported features:
- 6-minute time frames. 1-minute frames are transmitted instead.
- Full-year DST in the
dst_nextfield. Time and current DST information can be transmitted in full-year DST situations successfully, but thedst_nextfield will be incorrectly set to0x23(DST transition occurs at a different time). - Negative leap seconds. All leap seconds to date have been positive.
- Message frames. These are special, non-time messages that are not intended use of this module.
