why my calculated field does not always work correctly

Hi,

I have a calculated field using javascript to calculate the number of workdays between created and resolved and works correctly most of the time however will sometimes calculate incorrectly. What is wrong here?

 

<!-- @@Formula: long days(Date start, Date end){ 
//Ignore argument check
Calendar c1 = GregorianCalendar.getInstance();
c1.setTime(start);
int w1 = c1.get(Calendar.DAY_OF_WEEK);
c1.add(Calendar.DAY_OF_WEEK, -w1 + 1);
Calendar c2 = GregorianCalendar.getInstance();
c2.setTime(end);
int w2 = c2.get(Calendar.DAY_OF_WEEK);
c2.add(Calendar.DAY_OF_WEEK, -w2 + 1);
//end Saturday to start Saturday
long days = (c2.getTimeInMillis()-c1.getTimeInMillis())/(1000*60*60*24);
long daysWithoutSunday = days-(days*2/7);
if (w1 == Calendar.SUNDAY) {
w1 = Calendar.MONDAY;
}
if (w2 == Calendar.SUNDAY) {
w2 = Calendar.MONDAY;
} 
return daysWithoutSunday-w1+w2;
} 
return days(issue.get("created"),issue.get("resolutiondate"))
-->

This looks like JMWE plugin, not ScriptRunner.

First, the formula uses Java, not JavaScript. Second, how exactly does it "sometimes calculate incorrectly"? We need more information in order to be able to help you.

it doesnt calculate the correct number of days on all issues sometimes it will show 1 day for something created today and solved 2 minutes later when it should be 0 and some show 9 days when it should be 5 days etc, others work perfectly so im not sure what the issue is.

How to manage many similar workflows?

I have multiple projects that use variations of the same base workflow. The variations depend on the requirements of the project or issue type. The variations mostly come in the form of new statuses ...
