DateTime.now incorrect offset on Windows after daylight savings time change
C:\>ruby -v -r date -e 'p Time.now; p DateTime.now' ruby 1.9.3p125 (2012-02-16) [i386-mingw32] 2012-03-12 14:55:05 -0700 #<DateTime: 2012-03-12T14:55:05-08:00 ((2455999j,82505s,413234000n),-28800s,2299161j)>
Note how the DateTime offset is -08:00 (incorrect) while the Time offset is -0700 (correct). This probably started happening yesterday, March 11, since that is the start of daylight savings time in the United States. My guess is that DateTime is somehow using the pre-2007 daylight savings time cutoffs (first Sunday in April instead of second Sunday in March), but that's not an informed guess.
This doesn't happen in ruby 1.9.2, so it's probably related to the new 1.9.3 date C extension (switch_hitter). Operating system is Windows XP SP3.

This should be fixed by r35002, so this ticket can be closed. I'll open a backport ticket for 1.9.3.
Edit: Looks like for backports, instead of opening a new ticket, the current ticket is moved. Can someone move this ticket to the Backport93 project?
