> Can't you keep both revision and date? Knowing that something was compiled 2 years ago means much more to me than a revision number which is meaningless to me unless i actually know what the current release is. Unless this test was performed at run time and told me how far out of sync this was with the master branch.

A revision is useful to me when it shows up
here on tech-talk along with a request for help.

Also, recent GCC complains about use of __DATE__ wrt.
https://reproducible-builds.org/ (which I agree with)
