CSV bulk import error for Origin Estimate

[Alfred Tan]

Hi, 

I am having similar issue as per below : 

https://community.atlassian.com/t5/Jira-questions/The-csv-bulk-import-doesn-t-seem-to-import-Original-Estimate/qaq-p/398228

Whenever I as key in the figure it become minute not hour. 

For example, I input 3600s for an effort of 1 Hour, but it end up showing 1 minute.
