I use Jira Cloud for Excel, where I execute the following JQL:
project = A AND issuetype = Bug and createdDate >= startOfMonth(0) and createdDate <= endOfMonth(0)
I see that filter shows list of bugs correctly but values for created/updated fields are shown in UTC format in Excel.
Example: Jira shows that the bug was created on 8/1/2024 9:00 AM (AEST). However, Jira Cloud pastes this information into Excel with the creation date in UTC format, which shows as 7/31/2024 11:00 PM.
