How to set the create date on imported issues

[daniel frentz]

Hello,

I'm currently writing a migration script to import tickets from our ticketing system into JIRA service desk. I am using the REST API to interact with JIRA. I can create calls, but how can I set the create date?

Thanks.

I forgot to mention that I am using the REST API.

Hello Daniel,
 
Try this script: 

import java.util.Date;

import java.util.Calendar;

import java.sql.Timestamp;

Date date= createdDate;
Calendar cal = Calendar.getInstance();
cal.setTime(date);
long millis = cal.getTimeInMillis();

Timestamp ts = new Timestamp(millis)

mutableIssue.setCreated(ts);
