Say I am having a timestamp 1140444334642 which is an epoch. I want this to be converted to something like "02/20/2006 19:35:34"
Woh ! That timestamp 1140444334642 actually made GNU date go back in time. Way before 1970. It went to 1906 ! I guess it must be some overflow, unless your epoch is different from a UNIX epoch.
What machine are you on ? From dictionary.com,
Anyway, if you have GNU date, then the answer to your question is
I guess perl would have an in built functionality to do the same thing.
Does anyone know a perl script/utility/etc. to calculate the time in seconds between two unix time stamps?
Any help will be appreciated.

Hi! Long time reader first time registered user and poster.
I've picked up some times and tricks and I'm at a dead end... I've parsed a log file for duplicates and printed only the two fields I need (duplicate entry and time stamp).
My question is, with this output, how would I script... (2 Replies)
Hi,
i have current timestamp, lets say "12:02:45" in an variable (var1) and another timestamp "08:30:00" fetched from table in another variable2 (var2).
How do i compare 2 timestamps in unix shell scripting.
if var 1 > var 2 then echo message.
Thanks in advance. (3 Replies)

lire::time
Time(3pm) LogReport's Lire Documentation Time(3pm)NAME
Lire::Time - parses and prints date in formats common to many log files.
SYNOPSIS
use Lire::Time qw/ syslog2cal /;
my @ltime = localtime;
while ( <LOGFILE> ) {
#...
my $time = syslog2cal( $m, $d, $t, @ltime );
}
DESCRIPTION
This module supplies many functions to parse dates in formats that you are likely to encounter in log files. It also offers many functions
to format epoch time in useful format.
NOTE ABOUT FUNCTION EXPORT
Altough all documented functions are exported by default to the caller namespace, you should explicitely import the functions you require
since exporting by default isn't recommanded by the perl modules guidelines.
DATE PARSING FUNCTIONS
This module includes several functions that convert between a more human readable date format and UNIX epoch time. All parsing functions
will return the number of seconds since Jan 1 1970 00:00:00 UTC and will die() when passed invalid arguments.
date2cal()
my $time = date2cal( $year, $month, $day, $time, [$timezone] );
my $time = date2cal( "2001 Mar 20 09:32:29 +0100" );
This function will convert a date in the date(1) default output format to UNIX epoch time. The function accepts either the date in a string
or splitted on whitespace. If the timezone component is omitted, the local timezone is assumed (usually based on the value of the TZ
environment variable).
syslog2cal()
my $time = syslog2cal( $month, $day, $time, $local_tm_ref );
my $time = syslog2cal( "Mar 11 13:21:00", $local_tm_ref );
This function will convert a date in the syslog default output format to UNIX epoch time. The function accepts either the date in a string
or splitted on whitespace.
Since the syslog format doesn't contain timezone information, the local timezone is assumed (usually determined by the TZ environment
variable).
The last argument is a reference to an array returned by localtime().
my $local_tm_ref = [localtime()];
It is used to determine the year.
clf2cal()
my $time = clf2cal( "[18/Mar/2001:15:59:30 +0100]" );
This function will convert a date as found in Common Log Format to UNIX epoch time.
DATE FORMATING FUNCTIONS
This module includes some functions to convert date in UNIX epoch time to some more human readable output. All functions will die() when
passed invalid arguments.
cal2rfc()
print cal2rfc( $time );
This function will convert a date in UNIX epoch time to the RFC822 format (used in email, for example). A RFC822 date looks like
Wed, 30 May 2001 12:45:13 +0000
The timezone offset specification will correspond to the local timezone (usually determined by the TZ environment variable).
cal2ymdhms()
print cal2ymdhms( $time );
This function converts a date in UNIX epoch time to a string of the form:
YYYYMMDDHHMMSS
This representation will correspond the time in the local timezone (usually determined by the TZ environment variable.)
getMonthName()
print getMonthName( 0 ); # Gives 'Jan'
This function takes as parameter a number (0-11) representing the month (as returned by localtime() for example) and will return the
English abbreviated name of that month ( Jan, Feb, etc. ).
