NAME

       pmUseZone - re-establish a reporting timezone

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmUseZone(const int tz_handle);

       cc ... -lpcp

DESCRIPTION

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

       The argument tz_handle identifies a reporting timezone as previously established by a call to pmNewZone(3) or pmNewContextZone(3), and this
       becomes the current reporting timezone.

SEE ALSO

       PMAPI(3), pmCtime(3), pmLocaltime(3), pmNewContextZone(3), pmNewZone(3) and pmWhichZone(3).

DIAGNOSTICS

       A return value less than zero indicates the value of tz_handle is not legal.

NAME

       pmCtime - format the date and time for a reporting timezone

C SYNOPSIS

       #include <time.h>
       #include <pcp/pmapi.h>

       char *pmCtime(const time_t *clock, char *buf);

       cc ... -lpcp

DESCRIPTION

       pmCtime is very similar to ctime(3), except the timezone used is the current ``reporting timezone'' (rather than the default TZ environment
       variable scheme), and the result is returned into a caller-declared buffer (rather than a private buffer).

       Like ctime(3) the time to be converted is passed via clock, and the result in buf is fixed width fields in the format:

		 Fri Sep 13 00:00:00 1986


       The result buffer buf must be at least 26 bytes long, and no attempt is made to check this.  pmCtime returns buf as the value of the  func-
       tion.

       The default current reporting timezone is as defined by the TZ environment variable, so pmCtime and ctime(3) will initially produce similar
       encoding of the date and time.

       Use pmNewZone(3), pmNewContextZone(3) or pmUseZone(3) to establish a new current reporting  timezone  that  will  effect  pmCtime  but  not
       ctime(3).
