Sprint dates inconsistencies and time zones. Stored internally in UTC-0 (GMT)

[David Leal]

I have my board time zone set to EST (UTC-5) and when I define the sprint dates I assume it will be in the same time zone, but it is not. For example if I set the sprint end date to 12:59 PM, then in Jira Advanced Roadmap (in my configuration I use target dates), then when that information is missing, it takes the dates from the sprint, and it is shifted by one day. I did several test and I realized that for 6:59 PM it doesn't change. So internally the date is stored in UTC-0 (Greenwich Mean Time (GMT)). I talked to my Jira Admin and our Jira instance is configured to CST (UTC-6) via the field: Default user time zone, so it is not taking that time zone neither. When you setup sprint start and end dates you don't have the option to specify time zone, I assumed my board or personal setting, but it is not working like that.

1. Is there any Jira Instance or Project settings specific configuration to control this?
2. Is it correct my assumption that the time zone for sprint is always UTC-0 regardless of the Jira instance time zone settings or board settings? Do I need to put the dates and time always assuming UTC-0?, but then it will show the wrong information in the backlog view in case there is date shift between my time zone and UTC-0.
3. Is it a bug?, because at the end it is confusing, because it shows one day in the sprint information view, but at the end is a different day. Was it reported?

Here the screenshot of my sprint dates:

Here Jira Advanced Roadmaps showing the dates shifted

I also tested using Automation that when I try to assign the sprint date to another date field, it is also showing the next day.

I searched for a similar posts, like this one: Issues with a Sprint START and END date that provide some explanation, but it doesn't really solves it. Similarly with Jira time zone post.

Thanks for any help,

David

David Leal, we are facing similar issue. We get an error saying 'Your local timezone doesn't match your Jira profile timezone' when we try to start sprint. However both on user profile and on 'Default user timezone' we have the same 'System Default(GMT: 00:00) UTC' timezone set. Were you able to find what is causing this?

BTW, we are on Jira Software DC 9.12.2.
