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.
