-      Previously, the default ISO 8601 format was hard-coded as in this
-      example: ``2010-09-06 22:38:15,292`` where the part before the comma is
-      handled by a strptime format string (``'%Y-%m-%d %H:%M:%S'``), and the
-      part after the comma is a millisecond value. Because strptime does not
-      have a format placeholder for milliseconds, the millisecond value is
-      appended using another format string, ``'%s,%03d'`` – and both of these
-      format strings have been hardcoded into this method. With the change,
-      these strings are defined as class-level attributes which can be
-      overridden at the instance level when desired. The names of the
-      attributes are ``default_time_format`` (for the strptime format string)
-      and ``default_msec_format`` (for appending the millisecond value).
