Breaking: #62925 - ExtJS Ext.ux.DateTimePicker removed

See Issue #62925

Description

The old ExtJS component Ext.ux.DateTimePicker has been removed and replaced with a bootstrap alternative. For technical reasons, the feature had to be removed. Thus the possibility to use "+3d" or "today" in input fields is no longer available.

Impact

Extensions which rely on Ext.ux.DateTimePicker will break.

Migration

Use the new bootstrap DateTimePicker component which can be loaded with require.js. Example implementations can be found in EXT:belog, EXT:scheduler and the FormEngine component of the TYPO3 CMS core.
