Seems that File.stat is not working well under Windows, specifically the mtime member.
This thing maybe related to local time (timezones) which should not because time which is used is unixtime.
On Mac works fine.

Windows: ruby 1.9.3p194 (2012-04-20) [i386-mingw32]
Mac: ruby 1.9.3p202 (2012-04-27 revision 35484) [x86_64-darwin11.3.0]

To reproduce:
  RESOURCES_DIR = File.expand_path(File.dirname(__FILE__) + "/test")
  MOD_TIME_CONTENTS = Time.at 1306527039

  def test_local_os
    Dir.mkdir(RESOURCES_DIR) unless (File.exists?(RESOURCES_DIR))
    file_path = "#{RESOURCES_DIR}/local_os_test.test"
    file = File.open(file_path, "w", 0777) do |file|
      file.puts("kuku")
    end
    file_stats = File.stat(file_path)
    p "MOD_TIME_CONTENTS: #{MOD_TIME_CONTENTS}."
    p "MOD_TIME_CONTENTS: #{MOD_TIME_CONTENTS.to_i}."
    p "file_stat.mtime: #{file_stats.mtime}."
    p "file_stat.mtime: #{file_stats.mtime.to_i}."
    p "File.mtime: #{File.mtime(file_path)}."
    p "File.mtime: #{File.mtime(file_path).to_i}."
    File.utime File.atime(file_path), MOD_TIME_CONTENTS, file_path
    file_stats = File.stat(file_path)
    p "file_stat.mtime: #{file_stats.mtime}."
    p "file_stat.mtime: #{file_stats.mtime.to_i}."
    p "File.mtime: #{File.mtime(file_path)}."
    p "File.mtime: #{File.mtime(file_path).to_i}."
  
    file_mtime = nil
    file = File.open(file_path, 'r') do |file|
      p "file.open.mtime = #{file.mtime}"
      p "file.open.mtime = #{file.mtime.to_i}"
      file_mtime = file.mtime
    end
  
    assert_equal(MOD_TIME_CONTENTS, file_mtime)
  
    # !!! This fails on windows with different timezone
    assert_equal(MOD_TIME_CONTENTS, file_stats.mtime)
  end

  Second assertion fails:
    1) Failure:
  test_local_os(BBFS::FileUtils::Test::TestTimeModification) [test/file_utils/time_modification_test.rb:89]:
  <2011-05-27 20:10:39 +0000> expected but was
  <2011-05-27 18:10:39 +0000>.
