Issue #3541 has been updated by Yui NARUSE.

Status changed from Open to Third Party's Issue
ruby -v set to ruby 1.8.7 (2010-06-23 patchlevel 299) [i686-darwin10.4.0]

DateTime#strftime is implemented with Ruby, so it is machine independent.
But Ruby 1.8's Time#strftime uses strftime(3), so it is machine dependent.
This is spec.

Ruby 1.9's Time#strftime uses own strftime C implementation, so it is machine independent.
But it means some extensions on some systems can't be used on 1.9.
