How would you find them?

People don't necessarily use "time_t". They might use "int" or whatever.

There is absolutely zero point to making this some kind of crazy
config option, because such an option will prove absolutely *NOTHING*.

Seriously. This whole concept is  completely stupid.

The only possible thing you can do is to

 (a) have an actual test-suite
 (b) set the time to 32+ bits
 (c) see what breaks

because otherwise it seems entirely pointless.

And no, we're not adding random crazy source modifications for pointless crap.
