For reproducible build, usually environment variable SOURCE_DATE_EPOCH will be
defined, and both GCC and Clang will use that timepoint for __DATE__ and
__TIME__.
BTW, many other things will break reproducible build if SOURCE_DATE_EPOCH is not
defined (e.g. ar without option D), so this wouldn't add extra effort.
