Logging duration with System.Diagnostics.StopWatch instead of using DateTime.Now

Still using two DateTime.Now calls to determine the duration of a certain call execution, like beneath?

DateTime start = DateTime.Now;
double secondsToLog = (DateTime.Now - start).TotalSeconds;

This is not at all necessary: using the StopWatch class. The StopWatch class is more efficient than any other solution provided or created in .NET since it uses low-level API calls and supports a high-resolution performance counter (when there is hardware and software support).

Stopwatch watch = new Stopwatch();
double secondsToLog = watch.Elapsed.TotalSeconds;
