PMLOCALTIME(3)          Library Functions Manual          PMLOCALTIME(3)

NAME         top

       pmLocaltime - convert the date and time for a reporting timezone

C SYNOPSIS         top

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

       struct tm *pmLocaltime(const time_t *clock, struct tm *result);

       cc ... -lpcp

DESCRIPTION         top

       pmLocaltime is very similar to localtime(3), except the timezone
       used is the current ``reporting timezone'' (rather than the
       default TZ environment variable scheme), and the result is
       returned into a caller-declared buffer (rather than a private
       buffer).

       Like localtime(3) the time to be converted is passed via clock,
       and the result contains the components broken out in the elements
       of the tm struct.

       pmLocaltime returns result as the value of the function.

       The default current reporting timezone is as defined by the TZ
       environment variable, so pmLocaltime and localtime(3) will
       initially produce a similar encoding of the date and time.

       Use pmNewZone(3), pmNewContextZone(3) or pmUseZone(3) to
       establish a new current reporting timezone that will affect
       pmLocaltime but not localtime(3).
