Adding an existing access key to another repository returns invalid information on expiry date on the UI

Issue Summary

This is reproducible on Data Center: yes

Steps to Reproduce

1. Add the access key for repository A and set the expiry days to X days
2. After two days, add the same access keys for repository A into repository B
3. The expiry date shown in the UI does not match the expiry date for repository A

Expected Results

The expiry date calculated in the UI for repository B should be the same as repository A

Actual Results

The expiry date calculated in the UI for repository B mismatch repository A

Workaround

There is no workaround, it is just a bug in the UI during calculation of expiry date when adding the access key. Once user click 'Save' button, the expiry date matches with the other repository.
