Merge #20437: fuzz: Avoid time-based "non-determinism" in fuzzing harnesses by using mocked GetTime()
8c09c0c1d18885ef94f79b3f2d073f43269bc95d fuzz: Avoid time-based "non-determinism" in fuzzing harnesses by using mocked GetTime() (practicalswift)
Pull request description:
Avoid time-based "non-determinism" in fuzzing harnesses by using mocked `GetTime()`.
Prior to this commit the fuzzing harnesses `banman`, `connman`, `net` and `rbf` had time-based "non-determinism". `addrman` is fixed in #20425. `process_message` and `process_messages` are left to fix: simply using mock time is not enough for them due to interaction with `IsInitialBlockDownload()`.
See [`doc/fuzzing.md`](https://github.com/bitcoin/bitcoin/blob/master/doc/fuzzing.md) for information on how to fuzz Bitcoin Core. Don't forget to contribute any coverage increasing inputs you find to the [Bitcoin Core fuzzing corpus repo](https://github.com/bitcoin-core/qa-assets).
Happy fuzzing :)
