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.

DIAGNOSTICS
