pmNewZone: establish a reporting timezone
NAME
pmNewZone - establish a reporting timezoneC SYNOPSIS
#include <pcp/pmapi.h>int pmNewZone(const char *tz);
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(7).
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.
DIAGNOSTICS
A return value less than zero indicates a fatal error from a system call, most likely malloc(3).
