LGTM. I think clang-tidy is pre-existing

Still getting a clang-tidy error despite //source/common/event:real_time_system_lib appearing in the deps of test_time_lib. I believe this is a flake/clang-tidy mistake? People have seen this before, not sure why. @lizan

This looks like fixing the issue.

Wow, thanks -- I should have scrolled more through the logs to see the pointer to test util. Fixed.
