Hello. I'm using limesurvey ver 1.90+ Build 9321. I'm trying to get rid of time in export data. I was trying to find the place (mostly in /admin/exportresults.php) where the date is being formated but I have no results

Can anybody help a little and point the direction?
If anybody needs: I changed the display format of the date and time in /admin/browse.php by adding lines:
//hide ip adress
if ("ipaddr"==$fnames[$i][0]) $browsedatafield=" ";
//delete time from default display format
if (strpos(' '.$fnames[$i][0],"date") && strlen($fnames[$i][0])>2)
$browsedatafield=substr($browsedatafield,0,strpos($browsedatafield,' '));
after the part:
if ( isset($fnames[$i][4]) && $fnames[$i][4] == 'D' && $fnames[$i][0] != '')
{
if ($dtrow[$fnames[$i][0]] == NULL)
$browsedatafield = "N";
else
$browsedatafield = "Y";
}
