I think I've solved and that it is a bug:
I noticed the time back by 1 hour, and replacing

<? php echo $ this-> html ('html.date', $ comment-> created);?>

with <? php echo $ this-> FormatDate ('l, j M Y G: i', strtotime ($ comment-> created));?>

you are the problem is resolved.

Hi there,

It seems that this is related to your current 'Server Time Zone' set on your site as you can see at backend>Global Configurations>Server>Locations settings as shown https://screencast.com/t/fdpDoXK6Dn. Please give it a check and see how it goes

is already set in the right way in the configuration section of Joomla, you have seen the code ch evi I posted, it's not bug them?

Hi there,

I have replicated it locally and it seems that those time is append correctly as you can see here https://screencast.com/t/UVpwjFL491aX. And it is based on the current timezone set that is rome, and mine current time is 4.12 and currently at rome is as shown https://screencast.com/t/UVpwjFL491aX.

Maybe you can provide us with FTP access for further check on this issues. Please advice.

I solved by putting the code I wrote above you

Hi there,

If that the case, maybe you can do template override or backup on those codes you made as this will not included on our next released version. Thanks for your understanding

I have put the data for ftp so take what you need, no problem, thanks a lot
