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.
__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 neg‐
ative 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.
Use pmNewZone(3), pmNewContextZone(3) or pmUseZone(3) to establish
a new current timezone that will effect __pmConvertTime.
PMAPI(3), pmNewContextZone(3), pmNewZone(3), pmParseInterval(3),
pmParseTimeWindow(3), pmUseZone(3), __pmParseCtime(3) and __pm‐
ParseTime(3).
