I had the same question, and I think I have found the solution:

There are two independent places to take control of:

1.

Line 90 of components/com_fireboard/sources/fb_timeformat_class.php
controls the format of the 'latest post' date in the lists of forums.
It looks something like this:
$usertime_format = "%m/%d/%Y %H:%M";

I think this is what you called a "front page".


2.

There are three lines in administrator/components/com_fireboard/language/english.php that look relevant. The important one is:

DEFINE('_DATETIME', 'm/d/Y H:i'; // originally DEFINE('_DATETIME', 'Y/m/d H:i';

This seems to control the format of the dates of posts appearing in lists of topics.


(There are two other places in this file where date formats can be changed, but I could not see what effect changing them had. Nevertheless, I changed them all to my preferred format.)

Thank you, works perfect.

Thx a lot for this post.

It works great. I changed these files for german date&time format:
1.
/administrator/components/com_fireboard/language/german*.php
[code:1]// originally DEFINE('_DATETIME', 'Y/m/d H:i');
DEFINE('_DATETIME', 'd.m.Y H:i');[/code:1]

2.
/components/com_fireboard/sources/fb_timeformat_class.php
translate day & month names and edit
[code:1]// originally $usertime_format = "%m/%d/%Y %H:%M";
$usertime_format = "%d.%m.%Y %H:%M";[/code:1]


3.
/components/com_fireboard/template/default/message.php
find
[code:1]time_since($fmessage->time , time() + ($fbConfig['board_ofset'] * 3600)); ?> ago[/code:1]
replace
[code:1]" " . _POSTED_AT ." " .date(_DATETIME,$fmessage->time); ?>[/code:1]

4.
I also had to set the "Country Locale" to de_DE under Site > Global Configuration > Locale

Thank's!

In addition to all the changes above, I still have to change the date format in english.php of the main joomla language directory in order for it to work.

public_html/language/english.php

Change line 428 and 429

From

DEFINE('_DATE_FORMAT_LC',"%A, %d %B %Y"; //Uses PHP's strftime Command Format
DEFINE('_DATE_FORMAT_LC2',"%A, %d %B %Y %H:%M";

To

DEFINE('_DATE_FORMAT_LC',"%A, %B %d %Y"; //Uses PHP's strftime Command Format
DEFINE('_DATE_FORMAT_LC2',"%A, %B %d %Y %H:%M";


This works for me, just thought someone might have the same problem and might need this.

FWIW - I have been tasked to change the date format (to "day, mm/dd/yyyy" & "day, mmm dd, yyyy" and the time format (from 24-hour to 12-hour) throughout the forum. I was able to get the intended results by making changes to the following files:

[root]/administrator/components/com_fireboard/language/english.php - lines 49-51 (shown with my changes):
DEFINE('_FB_DT_DATE_FMT','%m/%d/%Y';
DEFINE('_FB_DT_TIME_FMT','%r';
DEFINE('_FB_DT_DATETIME_FMT','%m/%d/%Y %I:%M %p';
(NOTE: lines 52-89 appear to define the names of months and days-of-the-week.)

[root]/language/english.php - lines 422-429 (shown with my changes):
DEFINE('_DATE_FORMAT','l, F d, Y'; //Uses PHP's DATE Command Format - Depreciated
/**
* Modify this line to reflect how you want the date to appear in your site
*
*e.g. DEFINE("_DATE_FORMAT_LC","%A, %d %B %Y %H:%M"; //Uses PHP's strftime Command Format
*/
DEFINE('_DATE_FORMAT_LC',"%A, %B %d, %Y"; //Uses PHP's strftime Command Format
DEFINE('_DATE_FORMAT_LC2',"%A, %B %d, %Y %r";

[root]/components/com_fireboard/template/default/view.php - line 1007 (shown with my changes):
/*$msg_date = date(_DATETIME, $fmessage->time);*/
$msg_date = date('l, m/d/Y h:i A', $fmessage->time);
(NOTE: this was suggested previously in this thread)

[root]/components/com_fireboard/template/default/latestx.php - line 168 (shown with my changes):
echo "" . date('l, m/d/Y h:i A', $latestPostTime) . "";

This has worked for my Forum where dates/times are displayed. The last one (latestx.php) affects the display when clicking "Show Latest Posts".

Unfortunately this doesn't work for me. As soon as I edit the english.php file in fireboard then entire thing goes blank.

I've read through this thread several times, and searched through others online on this topic. I've made all of the changes mentioned in my attempt to get dates to display mm/dd/yyyy H:M

And it works ... but only on the page that lists all of my Fireboard forums. When you click on any specific forum, all the posts still show as yyyy/mm/dd H:M

I'd really like to change this. And also another thing mentioned in another thread but related, which is the "xx Weeks, x Days ago" thing. I'd rather have the actual time of the post, in mm/dd/yyy H:M format

Any help would be greatly appreciated

To get in the message "posted at" (date and time), instead of "posted xx days and xx minutes ago" go to

/components/com_fireboard/template/default/message.php

find:

$msg_time_since = _FB_TIME_SINCE;


and replace with

$msg_time_since = " " . _POSTED_AT ." " .date(_DATETIME,$fmessage->time);
