Divide the approximate circumference of the Earth (24890) miles,
by the number of time zones (24) to get the width in miles of the
average time zone at the equater (approx. 1040 miles).  Divide
1040 miles by the approximate speed of light (186282 miles/sec)
to get the MINIMUM time a ground wave time it would take an RF
signal to travel that 1040 miles.  You'll get almost .006 seconds,
or almost 6 mS.  Actually it's 5350 uS per 1000 miles, ground wave!
Gosh awful slow, eh?
