This is what valgrind build does, so as to produce:
$ valgrind --version
valgrind-3.14.0.GIT
$ valgrind --version -v
valgrind-3.14.0.GIT-f1ff8597ef-20170919
The final "official" 3.14.0 release will (should) not have the
.GIT part (but will keep the short sha1 and date in -v output).
The date of last commit was recently added in the --version -v output.
There is also a trailing X added to the date if there are some diffs
between workdir and index, or index and HEAD.
See auxprogs/make_or_upd_vgversion_h and Makefile.am in valgrind
sources for details.
