How can i force date / time changes on my jira instance ?

[Kou Ssi]

I changed the date and time format from Administrator > Feel & Look > Date/Time 
However my changes won't apply after the instance starts i want to force the default values to change ( override them ) via the jira-config.properties any ideas on how to do that ?

Hello @Kou Ssi 

If you go to Administration -> System Info, you can see the system date as JIRA sees it. Is it correct? Is the timezone listed there correct?

If not, then probably the operating system date is wrong as well.

If the JIRA server is in a different timezone and you only want JIRA to run with Australian timezone, then you could set the -Duser.timezone=AU Java property on startup:

The thing is i changed the date and time format it displays when I hover the cursor on the date label (it shows the exact format I defined) but it's not displayed on the UI 

I need a way to disable the default date value using jira-config.properties  file but I don't exactly know how

Are you talking about relative dates? Like when it says Today or Yesterday?

[Kou Ssi]

yees exactly the one that says ( 2 hours ago / yesterday /... ) i want to change that to be in the format dd/mm/yyyy hh:mm a

add the following to your jira-config.properties file and restart jira

jira.lf.date.relativize = false
