       This documentation is intended for internal Performance Co-Pilot
       (PCP) developer use.

       provide different semantics at some point in the future.

DESCRIPTION         top

       __pmParseCtime reverses the asctime(3) function.  It accepts a
       string specifying a time, and fills in the given tm structure.

       string is either a fully specified date and time in the format
       Day MMM DD HH:MM:SS YYYY (e.g "Mon Mar  4 13:07:47 1996") or a
       partially specified date and time like "1996", "Mar 1996", "Mar 4
       1996", "Mar", "13:07:47", "13:07", "Mar 4 13:07:47",....  For a
       partially specified date and time, the order of the fields must
       be preserved and missing fields are filled in from the current
       date and time.

       The seconds component (SS) may be a floating point number, for
       example the time "13:07:47.5".  The 12 hour clock is also
       supported, so "13:07" and "1:07 pm" are equivalent.

       __pmParseCtime returns 0 if successful.  It returns -1 and a
       dynamically allocated error message string in errmsg, if the
       given string does not parse.  Be sure to free(3) the error
       message string.

       The tm structure returned in rslt should only be used as an
       argument to the __pmConvertTime function, as it contains encoded
       information that will only be correctly interpreted by
       __pmConvertTime.
