Obviously something with DST but I can not figure out why? To me 3600 epoch seconds remains 01:00, DST or not.
From the gawk man pages:
Code:
strftime([format [, timestamp]])
Formats timestamp according to the specification in format. The timestamp should be of the same form
as returned by systime(). If timestamp is missing, the current time of day is used. If format is
missing, a default format equivalent to the output of date(1) is used. See the specification for the
strftime() function in ANSI C for the format conversions that are guaranteed to be available. A pub‐
lic-domain version of strftime(3) and a man page for it come with gawk; if that version was used to
build gawk, then all of the conversions described in that man page are available to gawk.
Hi Everyone
i have a perl file below, one of the line is convert the pcho time to human readable format.
$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 <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":

strptime
STRPTIME(3) 1 STRPTIME(3)strptime - Parse a time/date generated withstrftime(3)SYNOPSIS
array strptime (string $date, string $format)
DESCRIPTION strptime(3) returns an array with the $date parsed, or FALSE on error.
Month and weekday names and other language dependent strings respect the current locale set with setlocale(3) ( LC_TIME).
PARAMETERS
o $date (
string) - The string to parse (e.g. returned from strftime(3)).
o $format (
string) - The format used in $date (e.g. the same as used in strftime(3)). Note that some of the format options available to strf-
time(3) may not have any effect within strptime(3); the exact subset that are supported will vary based on the operating system
and C library in use. For more information about the format options, read the strftime(3) page.
RETURN VALUES
Returns an array or FALSE on failure.
The following parameters are returned in the array

EXAMPLES
Example #1
strptime(3) example
<?php
$format = '%d/%m/%Y %H:%M:%S';
$strf = strftime($format);
echo "$strf
";
print_r(strptime($strf, $format));
?>
The above example will output something similar to:
03/10/2004 15:54:19
Array
(
[tm_sec] => 19
[tm_min] => 54
[tm_hour] => 15
[tm_mday] => 3
[tm_mon] => 9
[tm_year] => 104
[tm_wday] => 0
[tm_yday] => 276
[unparsed] =>
)
NOTES
Note
This function is not implemented on Windows platforms.
Note
Internally, this function calls the strptime() function provided by the system's C library. This function can exhibit noticeably
different behaviour across different operating systems. The use of date_parse_from_format(3), which does not suffer from these
issues, is recommended on PHP 5.3.0 and later.
Note
"tm_sec" includes any leap seconds (currently upto 2 a year). For more information on leap seconds, see the Wikipedia article on
leap seconds.
Note
Prior to PHP 5.2.0, this function could return undefined behaviour. Notably, the "tm_sec", "tm_min" and "tm_hour" entries would
return undefined values.
