`time.rs` is usually located in `components/profile_traits/time.rs`.
Trace templates are typically located in `~/Library/Application Support/Instruments/Templates`.
The supplied trace template must contain the "Points of Interest" instrument.
Output is written to standard output and should typically be piped to a new `.tracetemplate` file.
Example:
patch-trace-template.py \\
