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, pmNewCon
textZone 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 iden
tify the current reporting timezone that may be used in a
subsequent call to pmUseZone(3) to restore this reporting
timezone.

DIAGNOSTICS
