PMNEWZONE(3)						     Library Functions Manual						      PMNEWZONE(3)

NAME

       pmNewZone - establish a reporting timezone

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmNewZone(const char *tz);

       cc ... -lpcp

DESCRIPTION

       The current reporting timezone affects the timezone used by pmCtime(3) and pmLocaltime(3).

       The argument tz defines a timezone string, in the format described for the TZ environment variable, see environ(5).

       pmNewZone  sets	the  current reporting timezone, and returns a value that may be used in a subsequent call to pmUseZone(3) to restore this
       reporting timezone.

       ron(5).

DIAGNOSTICS

       A return value less than zero indicates a fatal error from a system call, most likely malloc(3C).

NAME

       pmLocaltime - convert the date and time for a reporting timezone

C SYNOPSIS

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

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

       cc ... -lpcp

DESCRIPTION

       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).
