Описание (Description)
__pmConvertTime accepts a tm structure that has been filled in by
__pmParseCtime(3) and a reference time point origin, and fills in
the given rslt structure with the time the user meant when he
specified a partial ctime or positive or negative time interval.
Typically, the argument origin is the start time for a set of
PCP archive logs, unless the user specified a negative interval
offset, in which case it is the end time of the log.
__pmConvertTime returns 0 if successful. It returns -1 and
writes an error message to stderr, if an error is detected.
Use pmNewZone(3), pmNewContextZone(3) or pmUseZone(3) to
establish a new current timezone that will effect
__pmConvertTime.
