Description
Performs a timed execution of Func or Proc and prints the execution times.
If the specified method is a function (Func), Trace returns the result of the execution of that function.
The optional parameter of type TLogToken of the specified method can be used to mark specific points where timestamps should be taken, in addition to the timestamp of the complete execution of the specified method.
