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 pmUseZone(3) to restore this reporting timezone.

DIAGNOSTICS

       PM_ERR_NOCONTEXT
              the current PMAPI context is not valid

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