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

       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.
