Module development and code questions

hello, I'm working in a module, and I have to store dates and times of some events, but I want to store the UTC instead of the local time, because I want to show the events in the timezone of the users....

There is any function in drupal for timezone conversion?

Is the forum module bust in 4.6? Ive been building a site and have just started on the forum section and have a couple of rather major problems:

- forum posts are promoted to the front page by default
- forum posts are not displayed in the forums

Is the forum known to work in 4.6?

Drupal 4.7:
I am making a module which specifies a new node type. But I do not wish this node type to have a link in the "create content" page. I did not include a hook_menu function at all, however my new node type still shows up on the "create content" page.

How can I suppress this link?
Thanks!

Hi,
I have worked hard to produce a working module, which is great from my point of view. As I wanted to share it, I was aiming to create a project on this website. I tried once to fill fields that I was able to, without any success of creation. I have no idea of what was wrong, but it didn't work.

I was stumbling through the handbook looking for info on using the CVS. I thought I'd examined most topics, and finally tried the "Bazaar-NG" topic.

So if this is the CVS software, what is ViewCVS? Are they the same? Are they alternatives?

Is there a module that is available that can put random or select images on the front page (in the center) with comments?
