pmNewContextZone - establish a reporting timezone based on a PMAPI
context
#include <pcp/pmapi.h>
int pmNewContextZone(void);
cc ... -lpcp
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.
