Date format is wrong in the Update Engine for Metadata after clicking Apply button

Date format (creration date, last modification date, last publication date) is wrong after clicking on "Apply" button in the Update Engine - Metadata.
How to reproduce:
1) Open an update engine
2) Switch to the Metadata (see screenshot-1.jpg)
3) Click on "Apply" button
4) The dates lose their format and just display date in milliseconds (see screnshot-2.jpg)
