PMMKTIME(3) Library Functions Manual PMMKTIME(3)
__pmMktime - convert a tm structure to a calendar time
#include <time.h>
#include "pmapi.h"
#include "libpcp.h"
time_t __pmMktime(struct tm *timeptr);
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.
__pmMktime is very similar to mktime(3), except the timezone used
is the current ``reporting timezone'' (rather than the default TZ
environment variable scheme).
Like mktime(3) the time to be converted is passed via timeptr, and
the function result contains the calendar time (the number of sec‐
onds since 00:00:00 UTC, January 1, 1970).
The default current reporting timezone is as defined by the TZ en‐
vironment variable, so __pmMktime and mktime(3) will initially
produce similar conversions.
Use pmNewZone(3), pmNewContextZone(3) or pmUseZone(3) to establish
a new current reporting timezone that will effect __pmMktime but
not mktime(3).
mktime(3), PMAPI(3), pmCtime(3), pmLocaltime(3),
pmNewContextZone(3), pmNewZone(3) and pmUseZone(3).
