How to calculate the 2 system date fields in Jira like create date and updated date

I have written below code  for calculating the two system fields.

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

def createdDate = issue.getCreated()
log.warn("Date Created: " + createdDate)
def updatedDate = issue.getUpdated()
log.warn("Updated Date: " + updatedDate)
{
def daysDiff = createdDateValue - updatedDateValue
return daysDiff
}

Do you have an XML or database backup? It's the only way to get it back.

Another option is if you have a test environment that uses older data.
