Need to capture time stamp of remaining estimate

[rohit mat]

Hi,

I need to capture time stamp of remaining estimate whenever it's changes.

I have a script to which i can get time stamp of time spent.

import com.atlassian.core.util.DateUtils
import com.atlassian.jira.component.ComponentAccessor

def worklogManager = ComponentAccessor.getWorklogManager()
def worklogs = worklogManager.getByIssue(issue)
if (worklogs) {
def worklog = worklogs.last()
"${worklog.updated}"
}
else {
"No worklog defined"
}

Can anyone please give me script to capture time stamp of Remaining estimate.

Thanks,

Rohit
