Different reasons. First, you don't have worldwide coverage of LF
time-signals, even DCF-77 isn't covering all parts of Europe. Second,
these stations operate on different frequencies throughout the world and
might have different coding.

The japanese run a LF station. That's the reason, why they want to
switch off JJY: It's becoming superfluous.

Yes. At least my 7030 is running accurate, same accuracy like a
quartz-clock. While PC-clocks are very often extremely inaccurate.
