how can i display date and time minus six hours in a post. For example now it's 23/02/2016 14:54, I need to display 23/02/2016 8:54. I'm using this in function.php of my theme:

function displaydate(){
    return date('d/m/Y G:i');
}
add_shortcode('date', 'displaydate');

and then I add [date] in post, but how can I display six hours back? Thanks a lot.

    I'd recommend prefixing your shortcode, as date is a very generic name, and is likely to clash. Also, if your -6 hours is to adjust to your timezone, there are better ways of doing this using WordPress APIs rather than hardcoding the difference – Tom J Nowell Feb 23 '16 at 14:22

This is not a WordPress question, but to help you out:

function displaydate() {
    return date( 'd/m/Y G:i', strtotime( '-6 hours' ) );
}
add_shortcode('date', 'displaydate');

The shortcode itself should work fine.

  • Thanks fischi, it works fine. Now I have this code in my archive.php: <?php echo date_i18n('d/m/Y H:m', time()); ?>, how can I obtain same effect (six hours back)? – Klod Feb 23 '16 at 18:14

    just replace time() with strtotime( '-6 hours' ) – fischi Feb 23 '16 at 21:38
  • Mightn't it also be useful to include a call to date_default_timezone_set? Otherwise, if/when you move the site to a server in a different timezone, you might not be getting the result you want. – Jeff Cohan Feb 25 '16 at 16:19
