Changes for phpBB 3.0.4

OPEN includes/session.php

FIND

Code: Select all

		// Show date <= 1 hour ago as 'xx min ago'
ADD, BEFORE

Code: Select all

		// This will determine the correct DST setting for every date, should a user wish for automatic detection
		$date_cache[$format]['zone_offset'] = ($this->data['user_dst'] == DST_AUTO) ? $this->timezone + date('I', $gmepoch) * 3600 : $this->timezone + $this->dst;
This replaces the last change that had to be made to includes/session.php up to and including 1.0.5 (the big piece of code you had to replace)!

I have added this on a pretty much plain vanilla board 304 board and now I get this:

Parse error: syntax error, unexpected T_STRING in /home/ronnieja/public_html/RJDtesting/includes/session.php on line 2052


I get this same error if I add only that change or both of them
the other change being

Code: Select all

Find
Tip: This may be a partial find and not the whole line.

CODE:SELECT ALL
			$this->dst = $this->data['user_dst'] * 3600;
Replace With
Tip: Replace the preceding line(s) to find with the following lines.

CODE:SELECT ALL
			$this->dst = ($this->data['user_dst'] == DST_ON || $this->data['user_dst'] == DST_AUTO && date('I')) ? 3600 : 0;

OK....I will try it again

I will re-enter all the 105 code
This is on a new install as I have to remake all my mods on a new 304 board as the update killed it

Will advise later tonight

It depends on the server configuration - but generally speaking yes, it's mostly useless.

A few users suggested that I not install this again

Most of my board users are in Europe and so I am wondering if this is worth installing?

Wouldn’t my changing the 1 hour forward or backward in the ACP do the same thing for everyone instead of each user having to reset their time?

BTW....what is the best time to set the default board time for?

Thanx...this is a problem for a few mods such as my countdown timer as it set globally for the UTC that I have it set for now.

I’m thinking that since I have to reinstall all my mods, as the 303 & 304 updates killed my test board

BUMP

How to uninstall the SQL please?
