> No, I think it's very important to understand that local times in the future do not identify a point in time and that local times are not necessarily tied to any particular location.

I mean, they sometimes do. You might want to wake up at 7.00 AM in the morning regardless of what timezone you’re in, but if I ask Siri what time sunrise is tomorrow (very relevant for setting my alarm!) she better give it to me in local time taking time zones into account.

Another example: I’ve added all the F1 races and qualifications this year to my calendar (I’m a big fan) so I can easily check that the Italian Grand Prix at Monza starts today at 3.00 PM my local time. If I travel to another timezone, my calendar better adjust, or else I’ll miss the races.

That's my whole point really. We need both points in time and (date)times that are relative to some possibly unknown location. These concepts cannot be merged.
