Oracle Convert a future date into epoch seconds on HPUX system
Hi All,

I have scenario where i have to compare two dates.
I thought of converting them to epoch seconds and do a numeric comparison.
This works fine on Linux systems.

Code:
$ date -d '2015/12/31' +%s
1451538000
$ date +%s
1449159121

But we don't have -d option in HPUX.

What would be an alternate method to convert any given date to epoch seconds on HPUX systems?

Thanks in advance for your help!

Regards,
Veeresham

Hi jgt,
I don't have control over installing any package on the servers.
I am looking for some other alternative.May be some perl one liner kind of solution

Specific for the format example that you shown, i.e. YYYY/MM/DD

Code:
#!/usr/bin/perl

use strict;
use warnings;
use Time::Local;

my $date = shift || die;

my ($year, $month, $day) = split('/', $date);
$year = ($year<100 ? ($year<70 ? 2000+$year : 1900+$year) : $year);
print timelocal(0, 0, 0, $day, $month-1, $year), "\n";

Run as: perl epoch_time.pl 2015/12/31

You could try this assuming you have the -j option:-
OSX 10.7.5, default bash terminal...

date -j 'mmddHHMMccyy.ss' +%s

This gives up to the last second before the _New_Year_.
Code:

AMIGA:barrywalker~> date -r 1451606399
