When we make changes to time_t related code, how to verify that it works with an unsigned time_t type?
The way I do it in tzdb <https://www.iana.org/time-zones/repository/tzdb-latest.tar.lz> is to replace the system time_t and its related low-level functions. It's a pain, and it does the job, and it's hard to explain. I vaguely recall trying simpler tricks something like what you describe, but don't remember why I abandoned that; perhaps I was trying for something that would work outside glibc.
