The only reliable way of doing that is to use UTC as the "internal"
representation and translate to/from local time on external
display/input *only*.  In the case of org mode, the "internal"
representation is user-visible, so that can cause confusion and some
head-scratching. But *any* other method is going to be a nightmare
(damhikt).
