__pmConvertTime - convert tm structure to timeval structure

#include "libpcp.h"
int __pmConvertTime(struct tm *tmin, struct timeval *origin,
struct timeval *rslt);
cc ... -lpcp
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 accepts 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 he
specified a partial ctime or positive or negative time interval.
Typically, the argument origin is the start time for a set of
PCP archive logs, unless the user specified a negative interval
offset, in which case it is the end time of the log.
__pmConvertTime returns 0 if successful. It returns -1 and
writes 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.
