Having WinQuake display and use hundredths of a second will not improve the
accuracy of the P and S waves or the resulting information from the S-P time
difference. This is because the travel-time tables only go down to tenths of
a second. This also would require a major rewrite of WinQuake. There have
been times when I have wanted to zoom in and have an X-Scale of less then 1
second. But this don't happen very often so I have been holding off making
this change to WinQuake.
