PMNEWCONTEXTZONE(3) Library Functions Manual PMNEWCONTEXTZONE(3)
NAME
pmNewContextZone - establish a reporting timezone based on a PMAPI context
C SYNOPSIS
#include <pcp/pmapi.h>
int pmNewContextZone(void);
cc ... -lpcp
DESCRIPTION
The current reporting timezone affects the timezone used by pmCtime(3) and pmLocaltime(3).
If the current PMAPI context is an archive, pmNewContextZone uses the timezone from the archive label record to set the current reporting
timezone.
If the current PMAPI context corresponds to a host source of metrics, pmNewContextZone executes a pmFetch(3) to retrieve the value for the
metric pmcd.timezone and uses that to set the current reporting timezone.
In both cases, pmNewContextZone returns a value to identify the current reporting timezone that may be used in a subsequent call to pmUse-
Zone(3) to restore this reporting timezone.
