…change from Daylight Time to Standard Time?
I haven’t. It’s too much of a pain to stay up until 2 am to see it happen.
But I can’t help but wonder if the radio command from Colorado advances the clock 23 hours or backs it up 1 hour.
I know it’s inane to wonder about this, but I do. :mad:
Don’t feel bad, this is one of my must know questions as well. I have also asked people that had such a device and I can’t find anyone that knows the answer. I can’t figure out a good way for it to work.
My Casio Wave Ceptor advances the hands 11 hours (not 23 it’s not a 24 hour dial!). No I didn’t stay up - my watch didn’t pick up the signal that night and I had to tell it to do it manually the next morning 
I have a radio controlled alarm clock radio, and mine also didn’t pick up the change from BST to GMT. But mine has a little “sun” symbol on the display to show Daylight Saving Time is in operation. When it does pick up the signal, it just switches that mode off, but you can override it by pressing a button. When you do that, it just adds or takes off the hour.
Edit: oops, just realised you were asking about analogue watches/clocks. Never mind.
Semi-hijack: My new Wave Ceptor gets a 3-bar signal on the WWV beacon, but it doesn’t synch with the time signal. Any suggestions?
The relevant point being that the watch didn’t know about DST and I had to toggle DST manually. Fortunately, this is a distinct setting from the main time display.
I’m in New Orleans for work and the Hilton we’re staying at has the type of clocks that you CANNOT change the time on, it has a built in thingamajig that sets the time when you plug it in. Except it apparently doesn’t know that the DST change happened early this year, because the time is an hour off now. Obnoxious!
I received a nice mantel clock (automatic), and I have seen it make the DST changes. It always goes forward. So the one hour “forward” was a simple spin. The “back” an hour was an 11 hour spin.
I had an analog-face “atomic” radio wall clock. It advanced the hands 11 hours in discrete steps, when it worked. But it was a huge hassle to try to keep it working, and follow their bizarre instructions for establishing the right time zone, and experiment with locations I could hang it and still sometimes get a signal.
I actually think radio-synchronized clocks are a very good idea that still has not been executed correctly by any of several manufacturers I’ve tried. If they insist on adding more and more features to them, like alarms and thermometers and FM radio, the least they could do as add keeping time while they’re at it.
One of mine hasn’t changed yet.
