JIRA won't accept 24-hour time format when logging work



I want to change the displayed time format of the date picker when I log work to 24-hour format but it doesn't work.


I'm changing the settings in Genereal Config -> Advanced Settings. My current settings are: HH:mm %H:%M


I've read multiple documentations and tried multiple different settings but none of them worked. The date and time is still shown as follows:

MM/dd/yyyy - H:mm a

2/18/2021 - 3:25 PM


I want to have the following format:

dd.MM.yyyy - HH:mm

18.02.2021 - 15:25


It's not about the look and feel in general, this is already working. I'm talking about when loggin work.


How can I change this?


Thanks a lot in advance.


Kind regards,

Hi @Dominik Dürrbeck

this is actually a bug which was highlighted in a similar thread.
Please refer to the thread for further information - there you also find linked the bug which you can watch and vote for.
It is already "in progress" so a fix should not took so long.


Hey Daniel,


Thank you very much for your reply.


Now this is what I was looking for.


Have a great week :)

Problem still remains... although modifying on advanced system settings and on look and feel date/time, it does not respects the modified format and shows the "american" format.

When you log work, you're usually entering a duration, not a time.  Durations are not represented in a 12 or 24h format, they're a number of days/hours/minutes

So I'm a bit stuck on where you're entering this log - is it a start and end date/time pair somewhere?

Hey Nic, thanks for your reply. Yes I'm entering a duration in "Benötigte Zeit" (see screenshot below).


What I mean is "Startdatum" (Start date). There you can see my problem.


We are using JIRA Software and JIRA Service Desk in Cloud and this windows opens since using the new issue detail view. No setting I change seems to change the display of the date here.


Hey Alexander, thanks for your reply. I already saw this page and tried all these settings but none of them worked unfortunately.
