[time-nuts] Cell Modem CDMA Time String

With an older Cell Phone Protocol, we had used a multi-tech cell phone modem to parasitically (without using any minutes) get GPS synchronized time data from local cell phone towers. Any idea on how to do this with the next generation of cell phone protocols. _

[time-nuts] Where do people get the time?

in the 1930's you could call the local telephone operator - who would look at the wall clock at say the "electric time is" . meaning the time the generator synchronous wall clock read. Thomas D. Erb p:508-359-4396 f:508-359-4482 a:97 West Street, Med

Re: [time-nuts] Mains Frequency -again

You just need one of these analog master clocks. The pointer reads zero if pendulum time is equal to line frequency time. I assume mathematically it integrates the difference over time. https://electricclock.omeka.net/items/show/6 Thomas D. Erb www.electrictime.com

Re: [time-nuts] The need for quartz crystals and mains frequency

Re: [time-nuts] Mains Frequency

they use their internal microcontroller crystal as a reference." Actually I think all of my kitchen appliances use line frequency for time reference - it's so easy to count. Thomas D. Erb o:508-359-9684 p:508-359-4396 x 1700 f:508-359-4482 a:97 West S

[time-nuts] US Line Frequency - Time Correction

I was wondering if anyone could describe how the US power gird sets it's line frequency. I know there is a standard somewhere, a local operator just told me - he just synchs with the grid - but obviously that standard is set somewhere. Thomas D. Erb o:508-359-9684 p:50

[time-nuts] Garmin WNRO

Is there a listing of Garmin GPS devices that have a WNRO problem - their support page doesn't state which ones have a problem. We have used their 17HVS and 16xHVS units. Their website just says; "Our testing shows the vast majority of Garmin GPS devices will handle the WNRO without issues."
