Hi Everyone

$value=`awk 'BEGIN{print strftime("%c",1273236600)}' | tr -d '\n'`;
if image, if i have lots of pcho time value in a file, if i use this awk, strftime, then tr -d to remove the \n,... (2 Replies)
Hi,
I am facing one strange situation while using strftime() to get current date and time in C.
it leaks memory with %T
strftime(L_StrDate,30,"%d-%b-%C%y %T", localtime((time_t *)&tv.tv_sec)) ;
and when i use another option then no memory leak like
strftime(L_StrDate,30,"%d-%b-%C%y ... (3 Replies)
HI,
i wish to convert a millsec value to a readable string format.
the one option is to use strftime.
However this is a bit costly (1-5 micros).
is there a a faster way to do so with just string manipulation
(Note i have the date object which has the time details but wish o avoid strftime) (2 Replies)
Hello all,
I have the following code that seems to be misbehaving depending on the timezone setting (TZ Environment variable). It gives the correct value when TZ is in POSIX format and the wrong value when in OLSON format.
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

I frequently use awk time functions and am switching some scripts over to mawk. I don't have the mktime or strftime functions in mawk, but it appears that there is a way, as explained here in "Time functions":

So, simple... (10 Replies)

Date::Format(3) User Contributed Perl Documentation Date::Format(3)NAME
Date::Format - Date formating subroutines
SYNOPSIS
use Date::Format;
@lt = localtime(time);
print time2str($template, time);
print strftime($template, @lt);
print time2str($template, time, $zone);
print strftime($template, @lt, $zone);
print ctime(time);
print asctime(@lt);
print ctime(time, $zone);
print asctime(@lt, $zone);
DESCRIPTION
This module provides routines to format dates into ASCII strings. They correspond to the C library routines "strftime" and "ctime".
time2str(TEMPLATE, TIME [, ZONE])
"time2str" converts "TIME" into an ASCII string using the conversion specification given in "TEMPLATE". "ZONE" if given specifies the
zone which the output is required to be in, "ZONE" defaults to your current zone.
strftime(TEMPLATE, TIME [, ZONE])
"strftime" is similar to "time2str" with the exception that the time is passed as an array, such as the array returned by "localtime".
ctime(TIME [, ZONE])
"ctime" calls "time2str" with the given arguments using the conversion specification "%a %b %e %T %Y
"
asctime(TIME [, ZONE])
"asctime" calls "time2str" with the given arguments using the conversion specification "%a %b %e %T %Y
"
MULTI-LANGUAGE SUPPORT
Date::Format is capable of formating into several languages, these are English, French, German and Italian. Changing the language is done
via a static method call, for example
Date::Format->language('German');
will change the language in which all subsequent dates are formatted.
This is only a first pass, I am considering changing this to be
$lang = Date::Language->new('German');
$lang->time2str("%a %b %e %T %Y
", time);
I am open to suggestions on this.
CONVERSION SPECIFICATION
Each conversion specification is replaced by appropriate characters as described in the following list. The appropriate
characters are determined by the LC_TIME category of the program's locale.
%% PERCENT
%a day of the week abbr
%A day of the week
%b month abbr
%B month
%c MM/DD/YY HH:MM:SS
%C ctime format: Sat Nov 19 21:05:57 1994
%d numeric day of the month, with leading zeros (eg 01..31)
%e numeric day of the month, without leading zeros (eg 1..31)
%D MM/DD/YY
%h month abbr
%H hour, 24 hour clock, leading 0's)
%I hour, 12 hour clock, leading 0's)
%j day of the year
%k hour
%l hour, 12 hour clock
%L month number, starting with 1
%m month number, starting with 01
%M minute, leading 0's
%n NEWLINE
%o ornate day of month -- "1st", "2nd", "25th", etc.
%p AM or PM
%P am or pm (Yes %p and %P are backwards :)
%q Quarter number, starting with 1
%r time format: 09:05:57 PM
%R time format: 21:05
%s seconds since the Epoch, UCT
%S seconds, leading 0's
%t TAB
%T time format: 21:05:57
%U week number, Sunday as first day of week
%w day of the week, numerically, Sunday == 0
%W week number, Monday as first day of week
%x date format: 11/19/94
%X time format: 21:05:57
%y year (2 digits)
%Y year (4 digits)
%Z timezone in ascii. eg: PST
%z timezone in format -/+0000
%d, %e, %H, %I, %j, %k, %l, %m, %M, %q, %y and %Y can be output in Roman numerals by prefixing the letter with "O", e.g. %OY will output
the year as roman numerals.
