 *  Convert age to ascii
 *
 *  Purpose:
 *      This routine will convert the age ( as held in tim ) into an ascii
 *      string. The address of the string is returned to the user. The
 *      string is internally static and is of a fixed format
 *
 *      The string format is
 *
 *      xxx(null)  - if the age is valid.
 *      ***(null)  - if the age is unknown
 * 
 *
 *  Parameters:
 *      tim         Time to convert
 *
 *  Returns:
 *      Address of an internal buffer that holds the ascii age string
 *
