Change time format from am/pm to 24h doesn't affect my instance


I want to change the time format from am/pm to 24h.

According to the documentation ( I've changed the following:

Advanced Settingsjira.png

Look & Feel Settings

But the changes don't affect my cloud instance. 

Do you see here any misconfiguration?

Thanks for your help.

Kind regards, Patrick

I really want 24h format! No any clear documentation how to achieve that.

Hi @Patrick Roos,

under "Look and Feel" you choose dd.MM.YY

in you advanced setting I see dd/MMM/YY

Also what time format is set in you personal account settings? When you're in Cloud you need to double check you account information.

Hi @Svenja L. 

Thanks for your your answer. 

I've customized the advanced setting - but I don't affect my site :-( In the personal settings I've the same configuration like you.


My goal is to change this time format to 24h.



Thank you for your help.

Kind regards, Patrick

We have the same issue, despite the docs saying "H:mm" should be 24h, neither "H:mm" or "HH:mm" work, all times are still in am/pm format.

Like # people like this

I have the same issue, it looks like it might be related to the language that you have chosen according to their docs:

If so, are they expecting us to change our language to something like Greek or Russian to get access to 24h format in the issue view?? That would be ridiculous, maybe it's time to create a feature request...

When you go to Settings > System > General Configuration > Advanced Settings, it also says the same ridiculous warning about time format being dependent on language preferences:
