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

       These interfaces are not part of the PCP APIs that are guaranteed
       to remain fixed across releases, and they may not work, or may
       provide different semantics at some point in the future.

DESCRIPTION         top

       __pmConvertTime and __pmConvertHighResTime accept a tm structure
       that has been filled in by __pmParseCtime(3) and a reference time
       point origin, and fills in the given rslt structure with the time
       the user meant when specifying a partial ctime or positive or
       negative time interval.

       Typically, the argument origin is the start time for a set of PCP
       archives, unless the user specified a negative interval offset,
       in which case it is the end time of the archive.

       __pmConvertTime and __pmConvertHighResTime return 0 if
       successful.  They return -1 and write an error message to stderr,
       if an error is detected.
