3 Casio watches here -- 2 discovered DST last night (Monday), 1 still on ST. Prior time changes all 3 changed over the night the time changed.

[time-nuts] Re: WWVB Daylight savings
All three WWVB AM clocks I moved into my garage overnight did set to DST correctly overnight and I have moved them back into the house. The house now has radiant thermal barrier thermal insulation under the roof in the attic; this insulation has aluminum foil applied to one paper surface. When I had this additional insulation installed, the WWVB AM clocks throughout the house stopped setting time overnight until I moved them to the inside of outside walls; now, they all seem to set time but not necessarily the DST change for some reason. The garage does not have this insulation so the WWVB signal is stronger out there. I do wonder why these AM clocks will set time-of-day but not change with DST. But, that is always the case; some of the clocks do and some don't but it is not always the same clocks that don't. Applying the DST correction is just inconsistent. The new insulation also reduced the GPS signal inside my home substantially. I have two timing GPS antennas on the roof and two GPS antenna splitters so I can distribute the GPS signal; one supplies GPS upstairs and one downstairs. But, if I bring the car GPS navigator inside to update its software, it does not consistently get a GPS signal now with the new insulation. The new La Crosse Ultratomic BPSK clocks will set anywhere inside my home within 10 minutes (usually much less) any time of day when the C-cells are replaced. It is reported that the BPSK "signal strength" (actually modulation decoding) is 100 times that of the AM modulation. I wish there were more kinds of BPSK clocks available! Is anyone aware of any other BPSK WWVB clock? Larry On 3/14/2021 9:20 PM, David I.

I have 3 WWVB AM clocks that did not update DST overnight last night but one that did and two BPSK clocks that did. Par for the course. The BPSK clocks always set correctly within 10 minutes any time of day.I moved the clocks that did not update into the garage out from under the aluminum coated thermal barrier attic insulation; they will update overnight tonight.I'm in Southern California.

My clocks did update and I have one that lags by 2 weeks due to its very old internal software. It flips on the old date. WWVB was indeed down in the noise this afternoon as John mentioned.
