You have UNIX or Linux, therefore you have mktime and strftime. These functions are fairly standard.
You may have go upgrade your version of mawk to have them in that language.
I think what I have is the newest version of mawk available for my system:
How might I get it to recognize the functions I need? Or, for that matter, how would I verify their availability on my system? Regular awk can use those functions. Does it call the same C functions that mawk apparently does? Thanks again for the responses.
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.

As Brendan O'Conner writes in this blog, mawk is near 8 times faster than gawk, so I am going to give mawk a go, but I got errors when trying to print the length of an array in mawk using length() function, is it not supported in mawk? or there's another way to get the length of an array in mawk?

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)

Hi,
I want to calculate diff b/w these starttime and endtime with use of mktime. I need response time in milisecond. I am using mktime to get these times. last three digits are in milisecond

So, I do some file processing that generates very large numbers, such as total amount GETted from a busy web cluster in a month, etc. Mawk is awesome-- fast and easy. It's awk! But, there's a fatal flaw that I'd like to overcome. Apparently, %d maxes out at 2147483647. Here's sample output,... (11 Replies)
I'm trying to use AWK to filter on some dates in a field by converting them to Unix Time.
mktime(strftime(format,"6-FEB-2013 08:50:03.841")What is the proper format for my date strings as they appear in my database?
My first thought is %d-%b-%Y %H:%M:%Sbut I see the following issues:

wcsftime
WCSFTIME(3) BSD Library Functions Manual WCSFTIME(3)NAME
wcsftime, wcsftime_l -- convert date and time to a wide-character string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <wchar.h>
size_t
wcsftime(wchar_t *restrict wcs, size_t maxsize, const wchar_t *restrict format, const struct tm *restrict timeptr);
#include <wchar.h>
#include <xlocale.h>
size_t
wcsftime_l(wchar_t *restrict wcs, size_t maxsize, const wchar_t *restrict format, const struct tm *restrict timeptr, locale_t loc);
DESCRIPTION
The wcsftime() function is equivalent to the strftime() function, except for the types of its arguments. Refer to strftime(3) for a detailed
description.
While the wcsftime() function uses the current locale, the wcsftime_l() function may be passed a locale directly. See xlocale(3) for more
information.
COMPATIBILITY
Some early implementations of wcsftime() had a format argument with type const char *, instead of const wchar_t *.
SEE ALSO strftime(3), xlocale(3)STANDARDS
The wcsftime() function conforms to ISO/IEC 9899:1999 (``ISO C99'').
