I've had a request to allow users to switch from the 12-hour format to the the 24-hour format but I haven't been able to find that option anywhere. Does it exist?

The Date and time are displayed depending on the language that is used by default by the board language. But you can enable users to allow setting the forum language in the host settings.

How wound I go about finding out which languages include the 24-hour time format? I've tried three different Englishes so far and all still display the times in 12-hour.

Hi I am having the same issue. I have created new language xml, named Macedonian.xml. i have setting the following codes

language="Macedonian" code="mk" inside. It has been chosen as the default language and culture settings at the board, but still i have the last visit and current time in English format.

I also did the setting for the user but it does not help
Still i get this:
Тековно време: 10:34:00 AM.
Вашата последна посета: Wednesday, April 22, 2015 12:49:49 AM

is there a way how to solve it? As I understand the only way is that YAF is taking the settings automatically from the selected language - culture in board settings?
