Maybe a platform-dependent problem? (tzdata?)

Ubuntu 9.04, package ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]
=> working CORRECTLY - "+0900 (KST)"

Mac OS X 10.6.2, macport ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin10]
=> working INCORRECTLY - "+0800 (KST)"

Seems a bug of Mac OS X's strftime().

$ uname -v
Darwin Kernel Version 9.8.0: Wed Jul 15 16:55:01 PDT 2009; root:xnu-1228.15.4~1/RELEASE_I386
$ ./tz
tm_gmtoff = +0900, tm_zone = KST
tm_gmtoff = +0800, tm_zone = KST

Ruby 1.9 doesn't have this issue, since it uses missing/strftime.c.
