Steps to reproduce the issue

Login as administrator and go to user -> notes. Try to change the review time of a user note.

Expected result

The entered date will be saved and shown as the new review date.

Actual result

After entering and saving the new date, it gets converted like:

The day will ever be converted to the 20th.

The month stays the same as entered.

The year changes irregularly depending on the entry. (e.g. 2013, 2020,...)

Example: I enter 13.02.2019 and get the result 20.02.2013.

System information (as much as possible)

Additional comments

In administrator/components/com_users/tables/note.php

before storing to database "return parent::store($updateNulls);"

The value of $this->review_time has the proper value.

In database the review time in table _user_notes has the inproper value.

Changing it manually changes the displayed review time in user notes.
