3021809 - DefaultDateEditor changes date-time values when using Russian language (possibly other languages too)

Description:
Datepikers (when using Russian language) don't work correctly in the backoffice. If you enter the time and remove the focus, the time changes. This problem can be reproduced on OOTB in all BO widgets containing a datepicker if Russian language is selected.

Affected:

• Commerce Cloud v2 on 1905 or higher.

On Commerce Cloud v2 on 1905.15 the issue was happening, but on older 1811 there was no such problem due to fact that default date format was different
Russian format 1811: "16.09.2020 13:05:55" - Issue not happening.
Russian format 1905: "9 сент. 20 г., 12:01:51" - Issue happening.

• Possibly onPrem environments with susceptible date format coming from server
