NAME
       pmWhichZone - return current reporting timezone

C SYNOPSIS
       #include <pcp/pmapi.h>

       int pmWhichZone(char **tz);

       cc ... -lpcp

DESCRIPTION
       The current reporting timezone effects the timezone used by pmCtime(3) and pmLocaltime(3).

       pmWhichZone returns the handle of the current timezone, as previously established by a call to pmNewZone(3) or pmNewContextZone(3).  If the
       call is successful (i.e. there exists a current reporting timezone) then a non-negative integer is returned and tz is set  to  point  to  a
       static buffer containing the timezone string itself.

DIAGNOSTICS
       A return value less than zero indicates there is no current reporting timezone.
