NAME         top

       pmCtime - format the date and time for a reporting timezone

C SYNOPSIS         top

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

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

       cc ... -lpcp

DESCRIPTION         top

       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\n\0

       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 function.

       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).
