Hello,

This issue has been reported by Jeremy Evans to RubyInstaller project:

http://groups.google.com/group/rubyinstaller/browse_thread/thread/1d49ca41486bba89

This simple code exposes the issue:

ruby -v -rtime -e "puts Time.now.dst?; t = Time.now.to_s; puts t; puts Time.parse(t); puts Time.parse(t).dst?"

The following is the output of all the installed Ruby versions I have:

 pik tags mingw ruby -rtime -e "puts Time.now.dst?; t = Time.now.to_s; puts t; puts Time.parse(t); puts Time.parse(t).dst?"

As you can see, while parsed string return DST, the time for 1.9.1 is incorrect.

All other versions work correctly.

Maybe this is a missed backport to 1.9.1 branch?

Just tested ruby_1_9_1 branch:

ruby -v -rtime -e "puts Time.now.dst?; t = Time.now.to_s; puts t; puts Time.parse(t); puts Time.parse(t).dst?"
ruby 1.9.1p424 (2010-05-03 revision 27598) [i386-mingw32]
true
2010-05-10 18:23:17 -0500
2010-05-10 19:23:17 -0500
true

Same results.

Thank you.

Bumping this.

Any 1.9.1 maintainer that can look at this?

Seems to me a missed backport.
