Here is the perfect solution.
Keep the Jayco Clock but change it's mechanism so that it
automatically keeps perfect time for each Time Zone and also handles Daylight Savings Time.
You can set all your clocks from this clock because it's always correct.
Here is how:
1. Purchase the
Radio Clock Movement that fits into your existing clock off Amazon.
2. Take your wall clock off the wall and carefully disassemble it. What will remain is a circular container on the back. Trim the plastic on one side so your new mechanism will fit (see image for guide)
3. Remove the wall support plate (you won't use it), insert the new
Radio Movement. You'll need to install it upside down to fit into the plastic housing (doesn't matter), next attach the two arms on the front of the clock, adjust the slider to your correct Time Zone and finally insert the battery.
Soon the arms will start moving on their own to set the proper time. Don't worry that the arms seem to rotate 24 hours before stopping at the right time. Please allow an hour or so, for it to find nearest radio signal. As we travel through different Time Zones, all I need to do is pop it off the wall and move the slider to match ET,CT,MT,PT
Radio clocks synchronized to a terrestrial time signal can usually achieve an accuracy within a hundredth of a second relative to the time standard. Radio clocks depend on coded time signals from radio stations.
