NAME

       __pmConvertTime - convert tm structure to timeval structure

C SYNOPSIS

       #include <pcp/pmapi.h>
       #include <pcp/impl.h>

       int __pmConvertTime(struct tm *tmin, struct timeval *origin, struct timeval *rslt);

       cc ... -lpcp

DESCRIPTION

       __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 PCP archive log, 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.

NAME

       __pmMktime - convert a tm structure to a calendar time

C SYNOPSIS

       #include <time.h>
       #include <pcp/pmapi.h>
       #include <pcp/impl.h>

       time_t *__pmMktime(struct tm *timeptr);

       cc ... -lpcp

DESCRIPTION

       __pmMktime  is  very similar to mktime(3), except the timezone used is the current ``reporting timezone'' (rather than the default TZ envi-
       ronment 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  seconds
       since 00:00:00 UTC, January 1, 1970).

       The  default  current  reporting  timezone is as defined by the TZ environment 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).
