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.

I have two files and would like a report of where they match.
Example of file1:

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:

data::faker::datetime
Data::Faker::DateTime(3pm) User Contributed Perl Documentation Data::Faker::DateTime(3pm)NAME
Data::Faker::DateTime - Data::Faker plugin
SYNOPSIS AND USAGE
See Data::Faker
DATA PROVIDERS
unixtime
Return a unix time (seconds since the epoch) for a random time between the epoch and now.
date
Return a random date as a string, using a random date format (see date_format).
time
Return a random time as a string, using a random time format (see time_format).
rfc822
Return an RFC 822 formatted random date. This method may not work on systems using a non-GNU strftime implementation (kindly let me
know if that is the case.)
ampm
Returns am or pm randomly (in the current locale) using one of the formats specified in ampm_format.
time_format
Return a random time format.
date_format
Return a random date format.
ampm_format
Return a random am/pm format.
datetime_format
Return a random date and time format.
month
Return a random month name, unabbreviated, in the current locale.
month_abbr
Return a random month name, abbreviated, in the current locale.
weekday
Return a random weekday name, unabbreviated, in the current locale.
weekday_abbr
Return a random weekday name, abbreviated, in the current locale.
sqldate
Return a random date in the ISO8601 format commonly used by SQL servers (YYYY-MM-DD).
datetime_locale
Return a datetime string in the preferred date representation for the current locale, for a random date.
date_locale
Return a date string in the preferred date representation for the current locale, for a random date.
time_locale
Return a time string in the preferred date representation for the current locale, for a random date.
century
Return a random century number.
dayofmonth
Return a random day of the month.
UTILITY METHODS
Data::Faker::DateTime::timestr($format);
Given a strftime format specifier, this method passes it through to POSIX::strftime along with a random date to display in that format.
Perl passes this through to the strftime function of your system library, so it is possible that some of the formatting tokens used
here will not work on your system.
NOTES AND CAVEATS
Be careful build timestamps from pieces
Be very careful about building date/time representations in formats that are not already listed here. For example if you wanted to get
a date that consists of just the month and day, you should NOT do this:
my $faker = Data::Faker->new();
print join(' ',$faker->month,$faker->dayofmonth)."
";
This is bad because you might end up with 'February 31' for example. Instead you should use the timestr utility function to provide
you a formatted time for a valid date, or better still, write a plugin function that does it:
my $faker = Data::Faker->new();
print $faker->my_short_date()."
";
package Data::Faker::MyExtras;
use base qw(Data::Faker);
use Data::Faker::DateTime;
__PACKAGE__->register_plugin(
my_short_date => sub { Data::Faker::DateTime::timestr('%M %e') },
);
POSIX::strftime
See the documentation above regarding the timestr utility method for some caveats related to strftime and your system library.
