Post installation

Everything works fine with this:

format_date($node->event_start, 'custom', 'D. M d, Y g:i a', $node->start_offset);

But then I simply want to post PST, EST, etc instead of GMT + 800. I tried what php_date function said like this:

format_date($node->event_start, 'custom', 'D. M d, Y g:i a T', $node->start_offset);

The problem is that many of my users aren't able to understand the timezones translated as GMT + 800. Anyone have a solution for this?

im getting errors like
Fatal error: Call to undefined function: fscache_is_file_stored()

in /drupal4.6.3/modules/filestore2.module on line 427
Fatal error: Call to undefined function: fscache_add_uploaded_file()

in /drupal4.6.3/modules/filestore2.module on line 428

if these errors are simple to solve im sorry

In my site my requirements are
water marking capability

Can i get these from existing modules if yes what modules are suitable,otherwise what to do get these features.
I dont know where to put such type of problem ,forgive me if i'm posting it in wrong entry.
I hope i'll get the way!

How do I have RSS Content from other websites feed into the main body of the home page, and also remain within the body?

I would like to prominently display the most recent date that anything on the website was updated.

Alternatively, to simply more prominently display the date that the most recent story was written.

Is there an easy way to do this? Possibly in the nav bar?
