Date value is not copied with "Farm field value updater - Copy from another document"

The "Farm field value updater - Copy from another document" doesn't manage to copy date values from one page to another one.

Reproduction:

• Create two sub-wikis
• Create a class containing a date object and have a copy of it in all sub-wikis
• Create a page with an object of the previously mentioned class and have a copy of it in all sub-wikis
• Modify one page's date object value
• Copy this new value using "Farm field value updater - Copy from another document" in other sub-wikis
• See that the new value hasn't been copied in other pages

Notes:

• This procedure works for copying the value of a TextArea
• Using value "14/07/2023 23:12:12" with "Farm field value updater" works too.
