### Describe the bug, including details regarding any error messages, version, and platform. Noticing that I sometimes got unexpected slow rebuilds, I tried to dive a bit into ccache debug output and found out that by default the PCG headers use the `__DATE__` and `__TIME__` macros, which makes builds non-deterministic: https://github.com/imneme/pcg-cpp/issues/59 We should perhaps simply remove PCG's `struct static_arbitrary_seed`, which would make compilation caching more efficient. @benibus @bkietz @assignUser ### Component(s) C++ -- This is an automated message from the Apache Git Service.
