With a recent version of ksh (on a system that doesn't have a GNU date utility) in a terminal session where the default timezone is the US Pacific timezone, the following:
So, with a GNU date utility on a Linux system using a recent bash, the following might work:
Code:
Date_GMT=042720170740
TZ=CST6CDT date -d "${Date_GMT:0:8} ${Date_GMT:8:2}:${Date_GMT:10} GMT" '%m%d%Y%H%M'
If the timezone being used in your terminal session is already set to use US Central time zone, you can drop the TZ=CST6CDT at the start of the date command line.
PS: Note that a timestamp of 0740 GMT will NOT convert to a timestamp of 10:30:00 CST; with the given date, it would either convert to 2017-04-27 01:40:00 CST or, if you aren't in the parts of Indiana that don't observe daylight saving time, 2017-04-27 02:40:00 CDT. Getting this date format would need the date format string:
Code:
'%Y-%m-%d %H:%M:%S %Z'
instead of:
Code:
'%m%d%Y%H%M'

Hi,
I need to convert a number representing time in UTC seconds to a date. Ex:

I have tried the following perl command but it gives a different answer?
$ perl -e 'print scalar localtime(shift), "\n"' 3BE00B2C

http::date
HTTP::Date(3) User Contributed Perl Documentation HTTP::Date(3)NAME
HTTP::Date - date conversion routines
SYNOPSIS
use HTTP::Date;
$string = time2str($time); # Format as GMT ASCII time
$time = str2time($string); # convert ASCII date to machine time
DESCRIPTION
This module provides functions that deal the date formats used by the HTTP protocol (and then some more). Only the first two functions,
time2str() and str2time(), are exported by default.
time2str( [$time] )
The time2str() function converts a machine time (seconds since epoch) to a string. If the function is called without an argument, it
will use the current time.
The string returned is in the format preferred for the HTTP protocol. This is a fixed length subset of the format defined by RFC 1123,
represented in Universal Time (GMT). An example of a time stamp in this format is:
Sun, 06 Nov 1994 08:49:37 GMT
str2time( $str [, $zone] )
The str2time() function converts a string to machine time. It returns "undef" if the format of $str is unrecognized, or the time is
outside the representable range. The time formats recognized are the same as for parse_date().
The function also takes an optional second argument that specifies the default time zone to use when converting the date. This parame-
ter is ignored if the zone is found in the date string itself. If this parameter is missing, and the date string format does not con-
tain any zone specification, then the local time zone is assumed.
If the zone is not ""GMT"" or numerical (like ""-0800"" or "+0100"), then the "Time::Zone" module must be installed in order to get the
date recognized.
parse_date( $str )
This function will try to parse a date string, and then return it as a list of numerical values followed by a (possible undefined) time
zone specifier; ($year, $month, $day, $hour, $min, $sec, $tz). The $year returned will not have the number 1900 subtracted from it and
the $month numbers start with 1.
In scalar context the numbers are interpolated in a string of the "YYYY-MM-DD hh:mm:ss TZ"-format and returned.
If the date is unrecognized, then the empty list is returned.
The function is able to parse the following formats:
"Wed, 09 Feb 1994 22:23:32 GMT" -- HTTP format
"Thu Feb 3 17:03:55 GMT 1994" --ctime(3) format
"Thu Feb 3 00:00:00 1994", -- ANSI C asctime() format
"Tuesday, 08-Feb-94 14:15:29 GMT" -- old rfc850 HTTP format
"Tuesday, 08-Feb-1994 14:15:29 GMT" -- broken rfc850 HTTP format
"03/Feb/1994:17:03:55 -0700" -- common logfile format
"09 Feb 1994 22:23:32 GMT" -- HTTP format (no weekday)
"08-Feb-94 14:15:29 GMT" -- rfc850 format (no weekday)
"08-Feb-1994 14:15:29 GMT" -- broken rfc850 format (no weekday)
"1994-02-03 14:15:29 -0100" -- ISO 8601 format
"1994-02-03 14:15:29" -- zone is optional
"1994-02-03" -- only date
"1994-02-03T14:15:29" -- Use T as separator
"19940203T141529Z" -- ISO 8601 compact format
"19940203" -- only date
"08-Feb-94" -- old rfc850 HTTP format (no weekday, no time)
"08-Feb-1994" -- broken rfc850 HTTP format (no weekday, no time)
"09 Feb 1994" -- proposed new HTTP format (no weekday, no time)
"03/Feb/1994" -- common logfile format (no time, no offset)
"Feb 3 1994" -- Unix 'ls -l' format
"Feb 3 17:03" -- Unix 'ls -l' format
"11-15-96 03:52PM" -- Windows 'dir' format
The parser ignores leading and trailing whitespace. It also allow the seconds to be missing and the month to be numerical in most for-
mats.
If the year is missing, then we assume that the date is the first matching date before current month. If the year is given with only 2
digits, then parse_date() will select the century that makes the year closest to the current date.
time2iso( [$time] )
Same as time2str(), but returns a "YYYY-MM-DD hh:mm:ss"-formatted string representing time in the local time zone.
time2isoz( [$time] )
Same as time2str(), but returns a "YYYY-MM-DD hh:mm:ssZ"-formatted string representing Universal Time.
