[Healeys] USA Time

[Dallas Congleton]

Actually in some digital clocks the line frequency does matter very much. AC 
powered digital clocks use the line frequency of the power line instead of a 
quartz crystal to calculate time. Any variation in line frequency, will 
affect the digital clock's accuracy. Couple of scenarios where AC digital 
clock accuracy could go awry is it is used at a different line frequency 
than it is designed for - this can happen if you travel with an AC line 
clock and your destination country uses a different line frequency than your 
home country.
