You're just asking for frustration! '-}
Back in the 70's I developed manufacturing processs for the timekeeping modules in the Texas Instruments electronic watches. (Remember those red LEDs and having to push a button to read the time?)
We had a master clock phase-locked to the WWV atomic clocks -- with WWV time distrubuted all through the factory. This included a test set 'socket' (into which a watch module could be placed) that would automatically synch that module exactly with WWV.
My "on-the-arm test" watch contained a module that I had selected and tweaked for a drift of only milliseconds per month WRT to WWV. IOW, I wore a watch that I knew was one of the world's most accurate -- synched exactly to WWV time.
That turned out to be one of the most frustrating experiences of my life -- because, as I learned, almost no one else has the correct time -- or cares! Probably the worst offenders were the radio stations by which most folks checked their clocks/watches.
It was very common to see the hour roll around, and then hear on the radio, "At the sound of the tone, the time -- brought to you by Grimblegrotzynick's Bar and Grill and Auto Repair Shop, where you can blah, blah, blah... the time will be six o:clock....BEEP!
(Reminds me of the 'urban legend' about the phone operator and the guy who blew the noon whistle at the mill...) '-}
I finally gave up and just set my watch about five minutes ahead of WWV -- and thought about it no longer... I now wear the cheapest watch I can find! :-)
Keep your "MickeyMouse University watch" -- you're probably as nearly on time as anyone else! :-D
