FWIW, I ran the regressions tests some time ago(probably before that
change to glibc) . Since the tests are known
to be broken wrt. time issues anyway (as well as currency, math and sorting),
it's easy to overlook.

You're not "fixing" glibc, you're reintroducing non-standardized, upstream
removed behaviour. That's typically a very bad thing. If anything, it
demonstrates the importance of not using or relying on
unstandardized/undocumented behaviour (and given that time_t is pretty
restrictive anyway, you'll need something else to keep dates. It doesn't
even cover all living people, and definitely not historical dates).

The bug wasn't open for long, and was closed by someone else.

Also, notice that this was where the fix came from: The upstream
maintainers (some of whom work for us, others don't).
