in class/xoopsform/formdhtmltextarea.php
line 75 or thereabouts:
function XoopsFormDhtmlTextArea($caption, $name, $value, $rows=5, $cols=50, $hiddentext="xoopsHiddenText")
$rows value is the height basically, and columns is the width.. change these values to suit..
do the same for formtextarea.php
line 80 or thereabouts
function XoopsFormTextArea($caption, $name, $value="", $rows=5, $cols=50){
change these values to suit..
not sure in regard to the timezone tho.. other than enclosing it with an inline style tag in the template to reduce the font-size..
