How to make a custom field to show the ∆ between two dates

[Nick H]

Using a JMCF custom field I need to calculate the time past between two date fields with an mm/dd/yyyy hh:mm:ss. I need to do this inside of a groovy script inside the custom field w/o importing anything else in. 

1. What type of JMCF field should be used?
2. What should the formula/expression be?

Hi @Nick H 

This should work

Date date1 = issue.get("date1");

Date date2 = issue.get("date2");

if (date1 == null || date2 ==null)

  return null;

return (date1.getTime() - date2.getTime())/1000L;

 I think the field type is Calculated (scripted) Duration

Hi @Nick H ,

The most natural field type to pick is the Calculated Duration field, which will display its value in duration format (like  Jira's estimated time field). 

The formula should return a number of seconds, and you can use the secondsBetween(...) global function:

secondsBetween(issue.get("field1"),issue.get("field2"))

Thanks David, looks like this is promising... I messed up and one of the dates is the system "created" date and the other is a custom field that is just dd/mm/yyyy... is there a way to "trim" the system created date to just be dd/mm/yyyy using your formula? Or perhaps a ROUNDUP function similar to an excel formula to put in front of the whole expression? That would work too

Do you mean the custom field is a Date Picker, not a Date/Time Picker? In that case, are you just interested in a number of days between the two dates? If so, the easiest is to round up the Created date:

import org.apache.commons.lang3.time.DateUtils
def created = DateUtils.truncate(issue.created, java.util.Calendar.DAY_OF_MONTH)
secondsBetween(created,issue.get("field2"))
