Returns an instance of a TracingController
. This must be non-nullptr. The default implementation returns an empty TracingController
that consumes trace data without effect.

Use this method instead of 'cppgc::InitializeProcess' when using 'cppgc::DefaultPlatform'. 'cppgc::DefaultPlatform::InitializeProcess' will initialize cppgc and v8 if needed (for non-standalone builds).

Monotonically increasing time in seconds from an arbitrary fixed point in the past. This function is expected to return at least millisecond-precision values. For this reason, it is recommended that the fixed point be no further in the past than the epoch.
