Subject: [ruby-core:58516] [ruby-trunk - Bug #9119]	TestTime#test_marshal_broken_offset broken under MinGW


Issue #9119 has been updated by phasis68 (Heesob Park).


Finally, I fount the reason why I cannot reproduce the same result with Rubyinstaller test.
The timezone of Rubyinstaller test server is UTC-3 and my timezone is UTC+9.

The localtime(3) overflow check code returns yes for timezone from UTC-12 to UTC+0, whereas returns no for timezone from UTC+1 to UTC+13.

Here is a patch for the config test.
