I am trying to calculate the difference, in days, between the create date and a date custom field.

I am trying to calculate the difference, in days, between the create date and a date custom field.  This usually works but sometimes when there is an update for ScriptRunner the calculation goes off....by very large numbers.  For one issue, I expect a value of 36 and I am getting 3,055,174,244.

Can anyone see anything wrong with my script?  Or what may cause the script to work for a while but then stop?

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.Issue;
import java.util.Date.*

def customFieldManager = ComponentAccessor.getCustomFieldManager();
def dateFieldObject = customFieldManager.getCustomFieldObject('customfield_10803');
def intTiming=0.0;

def dateFieldObject2 = issue.getCreated();

if(issue.getCustomFieldValue(dateFieldObject) && issue.getCreated()) {
def dateValue = issue.getCustomFieldValue(dateFieldObject) as Date
def dateValue2 = issue.getCreated() as Date
return dateValue - dateValue2

}

This is a good question, and I don't know the answer, but my best guess would be that your environment is sometimes returning milliseconds instead of days.

Try an explicit cast to milliseconds and then recalculate the day value, e.g.

def dateValueInMs = dateValue.getTime()

def dateValue2InMs = dateValue2.getTime()

return (dateValueInMs-dateValue2InMs)/1000/60/60/24

Thank you!  I couldn't get the .getTime() to work for me, but I was able to adjust my calculation accounting for the milliseconds.  Just waiting for it to break again.

I appreciate your help!
