 * @param   clk  Output parameter for the clock in which the
 *               returned time is specified.
 * @return       0 on success, -1 on error.
 * 
 * @throws  EINVAL  `str` could not be parsed.
 * @throws  ERANGE  `str` specifies a time beyond what can be stored.
 * @throws  EDOM    The specified the was over a day ago.
 * 
 * @futuredirection  Add environment variable that allows
