PMNEWCONTEXTZONE(3) Library Functions Manual PMNEWCONTEXTZONE(3)
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.
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)
