 *             len        - [OUT] the length of parsed time period            *

 *             multiplier - [OUT] the parsed multiplier                       *

 *             base       - [OUT] the parsed time unit                        *

 *             error      - [OUT] the error message if parsing failed         *

 * Return value: SUCCEED - period was parsed successfully                     *
