Hell, considering that the WWVB (and WWV, for that matter) transmitters 
are just up the street from us, and broadcasting at 10,000-50,000 Watts, 
you could probably be able to tell time just from the way your own 
molecules are shaking...

WWV is the clock you 'hear' on shortwave radios and when you call (303) 
499-7111, WWVB is the clock that you could probably feel...  WWVB is 
what the Sams Club clocks listen to:

ObSysadminStory:  At my last job, my Sams Club atomic clock was hanging 
on the wall in my office/server room.  The RF noise in that room was SO 
bad, that the clock was unable to set itself, despite being probably 
less than ten miles from the 50kW transmitter...  Kinda scary, no?
