Use "main (void)" instead of "main (void)" to avoid GCC 4.9 warning:
tst-difftime.c:62:1: error: function declaration isn’t a prototype [-Werror=strict-prototypes]
main ()
^
tst-difftime.c: In function ‘main’:
tst-difftime.c:62:1: error: old-style function definition [-Werror=old-style-definition]

Since GCC 4.9 doesn't have __builtin_add_overflow:
In file included from tst-stringtable.c:180:0:

stringtable.c:185:7: error: implicit declaration of function ‘__builtin_add_overflow’ [-Werror=implicit-function-declaration]

return EXIT_UNSUPPORTED for GCC 4.9 or older.

I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.

This change adds new test to assess difftime's functionality by
adding some arbitrary offsets to current time_t value (read via
time).
If 64 bit time_t is supported, the same procedure is applied around
the threshold of Y2038 time overflow.
