$ENV{'TZ'} is not respected on localtime with perl-5.22.1 (Re: make test

[Makoto Fujiwara <makoto%ki.nu@localhost>]

I'm concerned perl (5.22.1) fails make test on 5 items.

Among below,
(2) is just a issue on modifed file one with REPLACE_PERL and by
    patch, and expected HASH'es are not updated.

Strange thing is (1). Please execute attached file on various
environment. Old perls seems OK, but at least 5.22.1 shows
all the same numbers indicating $ENV{'TZ'} is not respected on
localtime function.
