[PATCH] test-parse-datetime.c: accommodate a relatively strict gcc warning

[Jim Meyering]

Using this new code in coreutils exposed a minor problem,
due to its use of -Werror=missing-declarations:

    test-parse-datetime.c:97:1: error: no previous declaration for \
      'gmt_offset' [-Werror=missing-declarations]
    cc1: all warnings being treated as errors

I fixed it and some style issues like this:

Subject: [PATCH] test-parse-datetime.c: accommodate a relatively strict gcc
 warning

* tests/test-parse-datetime.c (gmt_offset): Declare function "static",
to avoid a warning from gcc's -Werror=missing-declarations.
Insert a few spaces-before-funcall-parenthesis.
