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.
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.

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS

DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk

...
}
