Question Compare dates

Hi,

I want to convert two datetime fields to find out if the difference is one hour, in linux I've done this by converting both the datetime values to unix epoch time and subtracting them to find out if the difference is more than 3600s, however this does not work in hp-ux.

I've these variable inside an awk script, and I'm getting the date values inside the script by:
Code:
"date +%Y%m%d%H%M%S" | getline current_time

Any ideas?

DateTime::Format::W3CDTF(3pm)				User Contributed Perl Documentation			     DateTime::Format::W3CDTF(3pm)

NAME
DateTime::Format::W3CDTF - Parse and format W3CDTF datetime strings SYNOPSIS
use DateTime::Format::W3CDTF; my $w3c = DateTime::Format::W3CDTF->new; my $dt = $w3c->parse_datetime( '2003-02-15T13:50:05-05:00' ); # 2003-02-15T13:50:05-05:00 $w3c->format_datetime($dt); DESCRIPTION
This module understands the W3CDTF date/time format, an ISO 8601 profile, defined at http://www.w3.org/TR/NOTE-datetime. This format as the native date format of RSS 1.0. It can be used to parse these formats in order to create the appropriate objects. METHODS
This API is currently experimental and may change in the future. o new() Returns a new W3CDTF parser object. o parse_datetime($string) Given a W3CDTF datetime string, this method will return a new "DateTime" object. If given an improperly formatted string, this method may die. o format_datetime($datetime) Given a "DateTime" object, this methods returns a W3CDTF datetime string. NOTE: As of version 0.4, format_datetime no longer attempts to truncate datetimes without a time component. This is due to the fact that "DateTime" doesn't distinguish between a date with no time component, and midnight. o format_date($datetime) Given a "DateTime" object, return a W3CDTF datetime string without the time component.

Support for this module is provided via the datetime@perl.org email list. See http://datetime.perl.org/?MailingList for details.
