Unfortunately, this one is inaccurate. It talks of impact to radio
controlled "Atomic Clocks", but does not mention WWVB, only WWV and WWVH.

Is there more of it? What I see makes no reference to WWVB.

Good Idea, John.
I'll do that.
Just to see what they say.

There's support in "over the air" ATSC digital TV signals for DST info,
but most TV stations aren't known for keeping their time information up
to date. There's a system time packet that has the GPS time, the number
of seconds difference between GPS time and UTC (and a lot of stations

Hi
I think there are a lot of ways to come up with a “local” WWVB signal that has
all the
DST stuff in it (or not if you prefer …). There’s not a lot of code or
development involved.
Even with the current shortage of parts, there are an ocean of dirt cheap MCU’s
and boards
to pick between.

"microprocessor" isn't a well defined term.
If you have an OS, use the time
I like Paul's idea, although there may be a risk of the LED's drive signal
not being accurately timed. Driving that LED accurately may have had
a low priority in the programmer's mind.
This should be independently checked for critical applications.

Currently, getting Daylight Savings Time status is easy using WWV or WWVB
since they have bits in the protocol marking status for the US, and in the
case of WWVB, impending change.
If both the HF and LF signals go away due to the proposed budget cuts, what
is the next simplest way (for something
