We are used to consider time-zones due to the useful subdivision of the Longitude in 24 steps and with that we all (should) agree.

The disagree generally comes when we talk about DST based on our main location (and thus experience), but the problem is intrinsic in the elliptic, so it must be addressed from another point of view (IMO): the Latitude.

I think that we should consider a further subdivision of the coordinate space; not only Longitude by 24, but also Latitude by something reasonable (e.g. every ±30° from the Equator; maybe not even of equal size but based on regions of the climate system).

With "time", we may acquaintance with this new kind of grid-based time-zones (which are easy to memorize/map-to given a basic knowledge of the Earth).

Any (useful) opinion ? :)

Meh, the existing boundaries are so distorted and politicized at this point, and people barely understand the reason for the longitude division that accounting for axis, wobble and equatorial differences are trivia by comparison. I say this as I get ready to depart SFO for Oahu then Guam, and regularly have business ranging across the entire Pacific.

Time zones don't actually form an even division of longitude into 24 zones, or even consistently follow lines of longitude at all.

Yeah and we got stuff like Newfoundland, which is in a half timezone. It's 30 minutes ahead of Eastern Time.
