My experience in the UK with inexpensive clocks receiving the 60 kHz
time signals from Rugby is that it's much harder to get an accurate time
off a liquid crystal display than audible pips.  Also it takes
approximately 0.05 secs for the display to change.  That may not seem
long, but a fast-moving satellite can travel a tenth of a degree in 0.05
secs.
