It should be accurate to the nearest millisecond to be useful as a coarse profiler.

No source file or test is named; start by locating the tcat entry point that formats timestamps and inspect how output timestamps are generated. Done means timestamped output includes millisecond precision, allowing the tool to serve as a coarse profiler.
