Comment Re:Can't we define the timezone as a UTC offset? (Score 4, Interesting) 105
I don't really agree. Timezones, DST, and TZ definitions are very well understood. Every year several (mostly small) countries make last-minute TZ changes and they get pushed out and handled; this is not new and untested tech. Sure we need some level of QA; we always need more testing! but changing a TZ file has very few side effects. All internal time info is already stored at UTC, so the TZ changes how it is displayed but not how it is consumed or calculated. MS did not push out critical changes for a rather major country, despite having sufficient time and incentive. And the change was not difficult or fragile.
