Here's the word that I received from Menlo Park on the timing error.

There seems to be no error at all on the web site.

If the events from this page:
http://quake.wr.usgs.gov/recenteqs/Quakes/quakes0.html
which shows the time in PDT is imported into WinQuake and converted
by WinQuake into UT, then the conversion could be in error if the
computer has already switched from PDT to PST.  I'm running some
computers with Win98SE and have yet to figure out how to change the
switch over time from PDT to PST.

Cheers,
John
