docs: Add a timer measurement for the given name.
  {@link Timer}s allow adding timer measurements, implicitly incrementing the count
  Timers count and measure timed events.
  The application decides which unit to use for timing.
  Miliseconds are suggested and some {@link ReportVisitor} implementations
  may imply this.
  
  @param name name of the {@link Timer}
  @param timing number of elapsed time units for a single measurement
