Here's some more information.  I actually have Ruby working correctly in
Windows now.  I left out an important step in updating a windows 
machine.  First use TZedit.exe ( 
http://www.softshape.com/download/tzedit.zip )
to set the correct dates for DST to begin and end.  Then (here's what I
didn't do) in Control panel choose Date and Time, choose the Time zone
tab.  Select another time zone other than the one you are in.  Click OK
Select Date and Time again, choose the Time zone tab.  Choose your 
actual time zone from the drop down list.  Click ok.  Ruby now works
fine.
