docs: Returns a name in the specified {@code style} of this {@code TimeZone}
  suitable for presentation to the user in the default locale. If the
  specified {@code daylight} is {@code true}, a Daylight Saving Time name
  is returned (even if this {@code TimeZone} doesn't observe Daylight Saving
  Time). Otherwise, a Standard Time name is returned.
  
  <p>This method is equivalent to:
  <blockquote><pre>
  getDisplayName(daylight, style,
  Locale.getDefault({@link Locale.Category#DISPLAY}))
  </pre></blockquote>
  
  @param daylight {@code true} specifying a Daylight Saving Time name, or
  {@code false} specifying a Standard Time name
  @param style either {@link #LONG} or {@link #SHORT}
  @return the human-readable name of this time zone in the default locale.
  @exception IllegalArgumentException if {@code style} is invalid.
