Version 0.2.0 (2025-01-31)

Release Notes

Added the ability to set a custom time from the command line rather than using the current time. This is a breaking change with v0.1.0 because the command line parameters have changed. The relevant changes can be seen below:

v0.1.0:

Short Form	Long Form	Value	Default	Description
-t	--timezone	Filename or TZ string	Signal-dependent	The timezone to use. More below.

v0.2.0:

Short Form	Long Form	Value	Default	Description
-z	--timezone	Filename or TZ string	Signal-dependent	The timezone to use. More below.
-t	--time	Date time string	Current time	The starting time to transmit.

Version 0.1.0 (2025-01-03)

Release Notes

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_next field. Time and current DST information can be transmitted in full-year DST situations successfully, but the dst_next field will be incorrectly set to 0x23 (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.
