pmiSetTimezone($value);

Python SYNOPSIS

from pcp import pmi

log.pmiSetTimezone(value)

Overview

As part of the Performance Co-Pilot Log Import API (see LOGIMPORT(3)), pmiSetTimezone sets the POSIX timezone string in the current context to value, which is stored in the archive label. In the absence of a call to pmiSetTimezone the source timezone defaults to the timezone of the localhost.

pmiSetZoneinfo sets the Olson (tzdata) timezone name for the archive, providing higher-fidelity timezone information than the POSIX string alone. If value is NULL, pmiSetZoneinfo auto-detects the Olson name for the current local timezone from the system timezone database; if no Olson name can be determined the call is a silent no-op. Passing an explicit Olson name such as America/New_York stores it directly without any lookup. The zoneinfo string is written into v3 archives alongside the POSIX timezone string.

Diagnostics

Both functions return zero on success, or a negative value that can be turned into an error message by calling pmiErrStr(3).
