I have JSD version 3.8 installed and I found, in the JQL autocomplete, these two functions, probably used for SLA metrics:
outdated()
withinCalendarHours()
For the last one, I found an issue opend at Atlassian for the lack of documentation. It seems the function exists, although the on-line course for certification as a JSD administrator explicitly says it does not!
For the first function (outdated()), I found nothing.
It's really frustrating not to be able to find out a thing about them. Can anyone enlighten me on this matter, please?
