I did a quick comparison between Lady Heather under Wine+Linux,
Lady Heather under Win7, and WWV.

The NTP time on my office machine agrees with WWV on 5 MHz
as closely as my eyes and ears can tell.  Linux is running its default
NTP, Win7 is running Meinberg (as I recall).

LH updates its time display about a moment later.
(Moment == 200milliseconds in Psychology.
I remember that because I got it wrong on a college psych quiz.)

I suppose one would have to use GPS 1pps to do much better than
NTP over a good internet connection.
