Use case

This calculated field returns the number of times a date-time field - in this example Expected delivery - has been changed.


Create a new Calculated Number 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.

Parser expression

Add the following expression:

Math expression for Calculated Number field:
{issue.cf13602} != null ? count(fieldChangeTimes({issue.cf13602},^0 != ^1)) : null
# If the Expected delivery field is set, the number of field changes (strictly speaking their timestamps) is counted.

{issue.cf13602} is the field code for the Expected delivery date-time field.
