vt740: Calendar load issue

Something is broken... When logging in to a clean vt740 and opening the Calendar view - there is a problem with the format of the date being fed to the DateTime::_construct():

Note how the date sent in the request to the feed action is 2021-05-02 (Y-m-d) but the date fed to the constructor is 02-2021-05 (d-Y-m)...
