Hi Everyone
i have a perl file below, one of the line is convert the pcho time to human readable format.
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, then assign it to the variable, this process is very slow.
any way to improve it? like perl has built in function, instead of `` the awk.
...
If you are looking for the equivalent of this -
in Perl, then you may want to use the "POSIX" module, which includes the strftime function -
The POSIX module is part of Perl's standard distribution, atleast on *nix systems. Otherwise CPAN is your one-stop shop.

Strange behaviour of the strftime() function from gawk (3.1.5):
$ awk 'BEGIN{print strftime("%T", 3600)}'
> 02:00:00
$ awk 'BEGIN{print strftime("%T", 0)}'
> 01:00:00
Obviously something with DST but I can not figure out why? To me 3600 epoch seconds remains 01:00, DST or not.

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)

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 by creating a language specific object and calling methods, see Date::Language
my $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 like %d, but a leading zero is replaced by a space (eg 1..32)
%D MM/DD/YY
%G GPS week number (weeks since January 6, 1980)
%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.
LIMITATION
The functions in this module are limited to the time range that can be represented by the time_t data type, i.e. 1901-12-13 20:45:53 GMT to
2038-01-19 03:14:07 GMT.
