[time-nuts] Personal time keeping...

Is anyone else old enough to remember when you would hear on the radio "Time 
at the tone, 5 o'clock.  Beep."  The tone was anywhere from half a second to 
one second long and it might have been hard to pin down if the beginning or 
the end of the tone was 5 o'clock but it was probably within a couple of 
seconds accuracy which was plenty good for setting your watch or the kitchen 
clock.  Why don't you hear that now a days?  Digital TV has latency which is 
dependant on the equipment used by the cable or satellite company and is 
somewhat variable between receiver manufacturers.  The engineer of our local 
public radio station told me that digital radio has 7 seconds delay.  When I 
asked the station manager if there were any plans to run studio time 7 
seconds ahead of real time so listeners would get accurate time he just 
frowned.
