Calculate duration and write to a text field

[Maria DePasquale]

I have two custom date fields (start and end).  I need to first calculate the duration (end-start) and then format that value like this:  d hh:mm:ss

Even if the duration is long, it would still be the above format so no months or years, just days hh:mm:ss.  If the duration was shorter than a day, the format would be hh:mm:ss.

I need to write the value to a text field.  So, the resulting text field would look something like this:  2  12:23:54  (2 days, 12 hours, etc)

I need to include this code in Post Function --> Scriptrunner.  Does anyone have a script handy that would help with this task?

You could use groovy.time.TimeCategory.minus(end, start) to get a groovy.time.TimeDuration

def endDate = new Date()
def startDate = new Date().parse("dd/MM/yyyy","11/1/2019")
groovy.time.TimeCategory.minus(endDate , startDate)

That script in the console outputs:  301 days, 9 hours, 44 minutes, 23.499 seconds

But you can combine different parts yourself to control the format:

def endDate = new Date()
def startDate = new Date().parse("dd/MM/yyyy","1/1/2018")
def duration = groovy.time.TimeCategory.minus(endDate , startDate)
"$duration.days $duration.hours:$duration.minutes:$duration.seconds"

Thanks for your suggestion @PD Sheehan.  This Post Transition script is what I implemented.  Note, it also subtracts hours due to Saturdays and formats the duration.  There are more imports than needed... I know.
