End-User Options - User-defined Date and Time display options

This modification allows a user to select their own date and time format. vBulletin 4 only has the option to specify one format for one language or different formats for different languages. This allows the user to select the format regardless of the language.

Date Formats
International Format yyyy-mm-dd (example: 1998-04-25)
Expanded International Format (example: Mon 25 April 1998)
US Format mm/dd/yy (example: 04/25/98)
Expanded US Format (example: Mon Apr 25th, 1998)
European Format dd/mm/yy (example: 25/04/98)
Expanded European Format (example: Mon 25th Apr 1998)

Time Formats
24-Hour Time Format (example: 23:15)
12-Hour Time Format (example: 11:15 PM)

This 4.x modification is based on an old 3.x modification (https://vborg.vbsupport.ru/showthread.php?t=97469) and modified with a few new date options and tested on vB4. I didn't invent this mod and just used the original mod and user comments in that thread to make it easy for use on vBulletin 4.

This was tested on 4.2.1 but it should work for any 4.x version.

Important: note the field names of the fields you just created. These can be different for your forum, depending on the other mods and plugins on your forum.

Any field option not mentioned above, use what you prefer.

Create new Plugin

You can either import the xml file or create the plugin manually.

Important: in the PHP code below or the imported xml plugin, you have to change the field names (switch ($vbulletin->userinfo['field#']) and replace field# with the names of the fields you created in the first step. For example: switch ($vbulletin->userinfo['field5']. To find the field names/numbers on your forum, go to AdminCP -> User Profile Field Manager and find the fields you created. The field names are in the Name column.

You can easily adjust the new fields and PHP code to remove or add any formats. The new Date and Time settings will show up under the General Settings for all users. Find more information about the possible date and time formats here: http://us1.php.net/manual/en/function.date.php

Great little fix and nice clear instructions. Thanks

If any one else wants to allow users to use the board defaults if they haven't picked a format or to explicitly use them, then you can make the following change to the two case statements:-

PHP Code:

....
case 'Forum Defaults':
    break;
default:
    // Do nothing
} 


I put the 'Forum Defaults' option at the top of the list of options in the two custom profile fields.
