Lluís,

time() will return a value relative to the epoch, which is epicentered in GMT. date() takes that value and returns a local time based on it. IE, date() knows about the computer's timezone and takes it into account.

Drupal's format_date() function uses gmdate() internally, which, unlike date(), does not do local timezone offsetting. gmdate() returns the formated date string in GMT. The reason format_date() does this is because it wants to return a time that has meaning to the individual user's location, which is not necessarily the computer's location, nor are all users always in the same timezone. Drupal does the timezone offsetting itself to allow a system default timezone and individual user configurable timezones too.

Double check your Drupal timezone settings at q=admin/settings/date-time and possibly your user timezone settings at q=user/$uid/edit

Making some research my problem is with format date:

$node->data_assentament -> 1247781600
date("d-m-Y H:i", $node->data_assentament) -> 17-07-2009 00:00
format_date($node->data_assentament,'medium') -> Dij, 07/16/2009 - 22:00

(I need the date in dd/mm/YYYY format)

Should I avoid format_date() or there is a better way to solve this?

I have created a custom node type. I have a date field which I created
as int in order to use it in views, being able to sort it, format,
etc....

My problem right now is that when inserting a node with one date, it
appears as "day before" when viewing the node. How should I save it to
avoid this problem?

My form looks like
 $arrayF=getdate(($node->data_paper>0 ? $node->data_paper : time()));
 $arrayF['month']=$arrayF['mon'];
 $arrayF['day']=$arrayF['mday'];
 $form['data_paper_array'] = array(
   '#type' => 'date',
   '#title' => 'Data Factura',
   '#default_value' => $arrayF,
   '#required' => TRUE,
   '#weight' => -9,
 );

My insert query looks like
 $dateF=$node->data_paper_array;
 $factura_tmsp=mktime(0,0,0,$dateF['month'],$dateF['day'],$dateF['year']);//
 $date['year']."-".$date['month']."-".$date['day'];
 $node->data_paper=$factura_tmsp;
 db_query("INSERT ......);

And my theme function:
 $output.="<li><b>Data Factura:</b>
".format_date($node->data_paper,'small')."</li>";


Any hint/advice? Thanks
