STRFTIME(3) Library Functions Manual STRFTIME(3)
NAME
strftime - format date and time
SYNOPSIS
#include <sys/types.h>
#include <time.h>
#include <string.h>
size_t strftime(buf, maxsize, format, timeptr)
char *buf;
size_t maxsize;
char *format;
struct tm *timeptr;
DESCRIPTION
The strftime() function formats the information from timeptr into the buffer buf according to the string pointed to by format.
The format string consists of zero or more conversion specifications and ordinary characters. All ordinary characters are copied directly
into the buffer. A conversion specification consists of a percent sign ``%'' and one other character.
No more than maxsize characters will be placed into the array. If the total number of resulting characters, including the terminating null
character, is not more than maxsize, strftime() returns the number of characters in the array, not counting the terminating null. Other-
wise, zero is returned.
Each conversion specification is replaced by the characters as follows which are then copied into the buffer.
%A is replaced by the full weekday name.
%a is replaced by the abbreviated weekday name, where the abbreviation is the first three characters.
%B is replaced by the full month name.
%b or %h
is replaced by the abbreviated month name, where the abbreviation is the first three characters.
%C is equivalent to ``%a %b %e %H:%M:%S %Y'' (the format produced by asctime(3)).
%c is equivalent to ``%m/%d/%y''.
%D is replaced by the date in the format ``mm/dd/yy''.
%d is replaced by the day of the month as a decimal number (01-31).
%e is replaced by the day of month as a decimal number (1-31); single digits are preceded by a blank.
%H is replaced by the hour (24-hour clock) as a decimal number (00-23).
%I is replaced by the hour (12-hour clock) as a decimal number (01-12).
%j is replaced by the day of the year as a decimal number (001-366).
%k is replaced by the hour (24-hour clock) as a decimal number (0-23); single digits are preceded by a blank.
%l is replaced by the hour (12-hour clock) as a decimal number (1-12); single digits are preceded by a blank.
%M is replaced by the minute as a decimal number (00-59).
%m is replaced by the month as a decimal number (01-12).
%n is replaced by a newline.
%p is replaced by either ``AM'' or ``PM'' as appropriate.
%R is equivalent to ``%H:%M''
%r is equivalent to ``%I:%M:%S %p'' .
%t is replaced by a tab.
%S is replaced by the second as a decimal number (00-60).
%T or %X
is equivalent to "%H:%M:%S" .
%U is replaced by the week number of the year (Sunday as the first day of the week) as a decimal number (00-53).
%W is replaced by the week number of the year (Monday as the first day of the week) as a decimal number (00-53).
%w is replaced by the weekday (Sunday as the first day of the week) as a decimal number (0-6).
%x is equivalent to ``%m/%d/%y %H:%M:%S'' .
%Y is replaced by the year with century as a decimal number.
%y is replaced by the year without century as a decimal number (00-99).
%Z is replaced by the time zone name.
%% is replaced by `%' .

STANDARDS
