TYPO3 Core

datetime fields are renderend differently (with timezone shift) in titels inside the recoord editor (record titel, inline record title).
See screenshots.

Elsewhere (Title in Record list in backend, also in Frontend and datetime edit field in backend) the rendering is correct, without timezone shift.
