This type of read-only custom field contains a value which is dynamically calculated from a custom math/time expression.
It can be used to obtain a date-time value depending on the value of the current issue or in any other issues (linked issues, sub-tasks, epics, stories, JQL selected issues, etc).
⚒️ Configuration
Configuring a calculated date-time field is straightforward. You have to configure a valid parser expression, which will "calculate" the output, and optionally a custom display format.
Create a new Calculated Date-Time Field (by JWT) custom field and name it properly.
Providing a description will help you to identify what the custom field does but this step is optional.
Math/time expression
Add a valid parser expression which will "calculate" the output.
Usually field codes will be used for this purpose.
%{issue.updated} #This example simply returns the timestamp (date-time) of when an issue was last updated.
The result of the calculation must be a valid timestamp. Read more about working with Dates, times and time zones.
Display format
Optionally choose a custom display format. This is extremely useful to enhance usability for end users.
