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 re‐ porting timezone. If the current PMAPI context corresponds to a host source of met‐ rics, pmNewContextZone executes a pmFetch(3) to retrieve the value for the metric pmcd.timezone and uses that to set the current re‐ porting 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)
