Examples of com.google.common.base.Stopwatch.elapsed()

com.google.common.base.Stopwatch.elapsed()
Returns the current elapsed time shown on this stopwatch, expressed in the desired time unit, with any fraction rounded down.
Note that the overhead of measurement can be more than a microsecond, so it is generally not useful to specify {@link TimeUnit#NANOSECONDS}precision here. @since 14.0 (since 10.0 as {@code elapsedTime()})

          // the multimap is guaranteed to be in sync with our timers while the Service.state() is
          // not.  Due to happens-before ness of the monitor this 'weirdness' will not be observable
          // by our caller.
          if (!stopWatch.isRunning() && !servicesByState.containsEntry(NEW, service) 
              && !(service instanceof NoOpService)) {
            loadTimes.add(Maps.immutableEntry(service, stopWatch.elapsed(MILLISECONDS)));
          }
        }
      } finally {
        monitor.leave();
