Incorrect date on successful upload

[appreciated]

Description

I noticed that upon successful upload, the date is set incorrectly. Instead of reflecting the current date, it is set to "2000-01-01".

Steps to Reproduce

1. Upload a component successfully in the Vaadin Directory using the API.
2. Check the date of the upload.

Example

See at my component

Observed Behaviour

• The date is incorrectly set to "2000-01-01" instead of the current date.
• This causes the new entry to show on the bottom and not to be selected by default after publishing:
  

Expected Behaviour

• The date-time should reflect the actual current date of the successful upload.
• The newest upload should show up at the top and not on the bottom
