Shouldn't this be `g_used_system_time |= bool(mocktime.count())`? This would allow to remove the `GetMockTime().count() == 0` check as well.

Ok, resolving for now.

If there is a preference about the style, my preference would be to have a clang-tidy (plugin) rule for this, instead of using human review resources.

I don't completely agree with this, since starting an old version of bitcoind with (for example)
`-signetchallenge=6a4c0901ff000000000000004c0151` would create an incompatible node. It would have a different network magic bytes and I think the `OP_RETURN` challenge would cause it to reject all blocks.

This issue is fixed in https://github.com/bitcoin/bitcoin/pull/31543. It could be worked around by setting the `LD_LIBRARY_PATH` environment variable.

The problem is that the goal of this PR was to speed up the RPC.
But if we benchmark that instead of just a subset of the task, i.e.:

You may have to rescan, when you load the wallet again, or restore from a backup. Otherwise, the transaction history (and balance) may be missing.

I meant, if you passed the extended challenge to an old version of bitcoin it would compute different magic bytes than if you passed the same challenge to an upgraded node.

The commit message and release notes say that there are corner cases being fixed in `-nosignetseednode` and `-nosignetchallenge`, but I can't seem to reproduce them, as the code disallows the two options:

```
❯ ./build/src/bitcoind -nosignetchallenge
Error: Error parsing command line arguments: Negating of -signetchallenge is meaningless and therefore forbidden

I verify that nodes accept blocks mined using the default signet challenge. This test includes one default signet node (2) and another node (6) configured with an extended signet challenge that uses the actual script OP_TRUE (accepts all blocks).

I added a comment with this explanation to the code.
