pmNewZone − establish a reporting timezone
int pmNewZone(const char *tz);
cc ... −lpcp
The argument tz defines a timezone string, in the format described for the TZ environment variable, see environ(5).
pmNewZone sets the current reporting timezone, and returns a value that may be used in a subsequent call to pmUseZone(3) to restore this reporting timezone.
A return value less than zero indicates a fatal error from a system call, most likely malloc(3C).
