7. Shell Programming and Scripting
I thought a program's elapsed time, some program language call it real time, should be the time of a program from start to finish. And it should be equal or longer than CPU time. This is true for the most of the cases. However, I do see some of my programs CPU time is longer than Elapsed time. ... (1 Reply)

PMCTIME(3) Library Functions Manual PMCTIME(3)
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).
